Branch: CURRENT, Version: 6.0nb1, Package name: ncursesw-6.0nb1, Maintainer: pkgsrc-users

The ncurses (new curses) library is a free software emulation of
curses in System V Release 4.0, and more. It uses terminfo format,
supports pads and color and multiple highlights and forms characters
and function-key mapping, and has all the other SYSV-curses
enhancements over BSD curses.

This package contains the wide character support libraries.

Log message:
Update to 6.0:

   This  release  is  designed  to  be source-compatible with ncurses 5.0
   through  5.9;  providing  a  new  application  binary interface (ABI).
   Although  the  source can still be configured to support the ncurses 5
   ABI,  the  intent  of  the  release is to provide extensions which are
   generally useful, but binary-incompatible with ncurses 5:
     * Extend  the  cchar_t  structure to allow more than 16 colors to be
       encoded.
     * Modify  the  encoding  of mouse state to make room for a 5th mouse
       button.  That  allows  one  to use ncurses with a wheel mouse with
       xterm or similar X terminal emulators.

   There are, of course, numerous other improvements, including
     * fixes made based on the Clang and Coverity static analyzers.
     * memory leak fixes using Valgrind

   The  release  notes  mention  some  bug-fixes,  but are focused on new
   features  and  improvements to existing features log since ncurses 5.9
   release.

   While  the intent of the release is to provide a new stable ABI, there
   are other development activities which are summarized below.
     * The  original  release  plan,  e.g., for "5.10" was to improve the
       MinGW port. Ultimately that was completed (wide-character support,
       mouse,  etc),  but  was  deferred  to focus on termcap support and
       performance  issues.  Also, pinpointing the problems with Console2
       took a while.
     * A  review  of  termcap  compatibility in 2011 led to several minor
       fixes  in  the  library  and improvements to utilities. To do this
       properly,  a  review of the various extent termcap implementations
       was needed.
       The [11]termcap library checker (tctest) (not part of ncurses) was
       one    result.    A   followup   review   of   performance   using
       [12]ncurses-examples in 2014 led to additional improvements.
     * Output buffering provided a further, but worthwhile distraction. A
       bug  report  in  2012  regarding  the  use  of  signal handlers in
       ncurses)  pointed  out  [13]a  problem  with  the  use  of  unsafe
       functions  for  handling SIGTSTP. Other signals could be addressed
       with workarounds; repairing SIGTSTP required a different approach.
       The  solution  required changing internal behavior of the library:
       how it handles output buffering.
       Now  ncurses buffers its own output, independently of the standard
       output.  A few applications relied upon the library's direct reuse
       of  the  standard  output  buffering;  however that is unspecified
       behavior  and  has  never been a recommended practice. Identifying
       these  applications  as  well  as  refining  the  change to permit
       low-level applications to work consistently took time.
     * Since  the introduction of the experimental support for 256 colors
       early  in  [14]2005  (released in [15]ncurses 5.5), there has been
       increased  user  interest. Almost all packagers continue providing
       the ncurses ABI 5 which cannot support 256 colors.
     * Symbol  versioning,  or  the  lack  of  it in ncurses, is the main
       reason why packagers would be reluctant to add a new ncurses ABI.
       This  release  provides  the  new  ABI along with script-generated
       lists  of versioned symbols which can be used for both ABI 5 and 6
       (with  distinct names to keep the two separate). This took time to
       development, as reported in [16]Symbol versioning in ncurses.

  Library improvements

  Output buffering

   X/Open curses provides more than one initialization function:
     * [17]initscr (the simplest) accepts no parameters.
     * [18]newterm accepts parameters for the stream input and output
     * [19]setupterm (the low-level function) accepts a parameter for the
       file descriptor of the output.

   They are documented in X/Open as if initscr calls newterm using stdout
   for   output  stream,  and  in  turn  newterm  calls  setupterm  using
   fileno(stdout)  for  the file descriptor. As long as an implementation
   acts  as if it does this, it conforms. In practice, implementations do
   what  is  implied.  This  creates  a  problem: the low-level setupterm
   function's  file  descriptor  is  unbuffered,  while  newterm  implies
   buffered  output.  X/Open  Curses says that all output is done through
   the  file  descriptor,  and  does  not  say  how  the output stream is
   actually used.

   Initially,  ncurses used the file descriptor (obtained from the output
   stream  passed to newterm) for changing the terminal modes, and relied
   upon  the  output  parameter of newterm for buffered output. Later (to
   avoid  using  unsafe  buffered  I/O  in  signal handlers), ncurses was
   modified  to use the file descriptor (unbuffered output) when cleaning
   up  on receipt of a signal. Otherwise (when not handling a signal), it
   continued to use the buffered output.

   That  approach  worked reasonably well and as a side effect, using the
   same buffered output as an application might use for printf meant that
   no   flushing   was   needed   when   switching  between  normal-  and
   screen-modes.

   There were a couple of problems:
     * to get good performance, curses (not only ncurses, but SVr4 curses
       in general) set an output buffer using setbuf or similar function.
       There  is no standard (or portable) way to turn that output buffer
       off,  and  revert  to  line-buffering.  The  [20]NCURSES_NO_SETBUF
       environment variable did make it optional.
     * to  handle SIGTSTP (the "stop" signal), ncurses relied upon unsafe
       functions.  That  is,  due  to  the  complexity of the feature, it
       relied  upon reusing existing functions which should not have been
       called via the signal handler.

   Conveniently, solving the second problem (by making ncurses do its own
   output  buffering)  also  fixed  the first one. But there were special
   cases to resolve: [21]low-level functions such as mvcur, putp, vidattr
   explicitly  use  the  standard  output.  Those  functions  were reused
   internally, and required modification to distinguish whether they were
   used by the high-level or low-level interfaces.

   Finally, there may still be a few programs which should be modified to
   improve their portability, e.g., adding an

fflush(stdout);

   when  switching  from "[22]shell" mode to "[23]program" \ 
(curses) mode.
   Those are fairly rare because most programmers have learned not to mix
   printf and [24]printw.

  Symbol versioning

   This  release  introduces symbol-versioning to ncurses because without
   it,  the  change of ABI would be less successful. A lengthy discussion
   will  be  presented  in  [25]Symbol versioning in ncurses. These notes
   summarize what has changed, and what can be done with the new release.

   Symbol-versioning  allows  the  developers  of  a library to mark each
   public  symbol  (both  data and functions) with an identifier denoting
   the  library  name  and  the  version for which it was built. By doing
   this, users of the library have a way to help ensure that applications
   do not accidentally load an incompatible library. In addition, private
   symbols can be hidden entirely.

   This   release   provides   sample   files   for  the  four  principal
   configurations  of  ncurses libraries: ncurses, ncursesw, ncursest and
   ncursestw. Each sample is given in two forms:

   ".map"
          These list all public symbols, together with version names.

   ".sym"
          These list all public symbols, without version names.

   The  sample  files  are generated by scripts which take into account a
   few special cases such as [26]tack to omit many of the ncurses private
   symbols  (beginning with "_nc_"). Here are counts of globals versus
   locals:

      Config   Symbols Globals Locals "_nc_"
     ncurses       976     796    180    332
     ncursesw     1089     905    184    343
     ncursest      979     804    175    358
     ncursestw    1098     914    184    372

   Although only four sample configurations are presented, each is formed
   by  merging  symbols  from  several  combinations  of configure-script
   options, taking into account advice from downstream packagers. Because
   they  are  formed by merging, the sample files may list a symbol which
   is  not  in  a  given package. That is expected. The samples have been
   tested  and  are  working  with  systems  (such as Fedora, FreeBSD and
   Debian)  which  fully  support  this  feature. There are other systems
   which  do  not  support the feature, and a few (such as Solaris) which
   provide incomplete support.

   The  version-naming convention used allows these sample files to build
   distinct libraries for ABI 5 and 6. Version names consist of
     * configuration   name,  e.g.,  "NCURSESW"  for  the  wide-character
       libraries
     * ABI version (if not 5)
     * library  name  for two special cases which have the same interface
       across configurations: "TINFO" and "TIC"
     * release version
     * patch date (for the release version)

   For  example,  running  nm  -D  on  the libraries in the ncurses6 test
   package shows these symbol-versions:

0000000000000000 A NCURSES6_TIC_5.0.19991023

0000000000000000 A NCURSESW6_5.9.20150530

   As  a special case, this release (which makes the final change for ABI
   5) is marked with release version 5.9 and patch date 20150530.

  Miscellaneous

   The new release has several improvements for performance and building.
   For instance:
     * several  files  in ncurses- and progs-directories were modified to
       allow  const  data used in internal tables to be put by the linker
       into the readonly text segment.
     * various improvements were made to building the Ada95 binding, both
       in simplifying the generated files as well as improving the way it
       uses gnatmake

   There are also new features in the libraries:
     * added [27]use_tioctl function
     * added  [28]wgetdelay  to  retrieve  _delay  member of WINDOW if it
       happens to be opaque, e.g., in the pthread configuration.
     * added [29]A_ITALIC extension.
     * added  form  library  extension [30]O_DYNAMIC_JUSTIFY option which
       can  be  used to override the different treatment of justification
       for static versus dynamic fields .
     * rewrote  [31]putwin  and  [32]getwin,  making  an extended version
       which  is  capable of reading screen-dumps between the wide/normal
       ncurses  configurations.  These are text files, except for a magic
       code at the beginning:

0       string          \210\210        Screen-dump (ncurses)

     * several changes to mouse support include:
          + added decoder for xterm SGR 1006 mouse mode.
          + added experimental support for "%u" format to terminfo.
          + improved  behavior  of  wheel-mice for xterm protocol: noting
            that  there  are only button-presses for buttons "4" and \ 
"5",
            so   there  is  no  need  to  wait  to  combine  events  into
            double-clicks .

   There   are   a   few  new  configure  options  dealing  with  library
   customization:
     * add "--enable-ext-putwin" configure option to turn on the extended
       putwin/getwin.  By default, this is enabled for ABI 6 and disabled
       with ABI 5.
     * add  "--enable-string-hacks" option to control whether strlcat and
       strlcpy  may  be  used. Because ncurses already does the requisite
       buffer-limit  checks,  this feature is mainly of interest to quiet
       compiler-warnings on a few systems.
     * add  configure  option  "--with-tparm-arg"  to  allow  [33]tparm's
       parameters  to  be  something more likely to be the same size as a
       pointer, e.g., intptr_t (again, the default is set for ABI 6).

  Program improvements

    Utilities

   Most of the termcap-related changes based on development of [34]tctest
   (termcap  library  checker)  are  implemented  in  the tic and infocmp
   programs   rather   than  affecting  the  library.  As  noted  in  the
   [35]discussion  of  tctest,  ncurses's  ability  to  translate between
   terminfo and termcap formats has been improved at different times, but
   subject  to  feedback from "real" termcap users. There are very few of
   those.  Nowadays,  virtually  all  termcap users are using ncurses (or
   NetBSD, with its own terminfo library) and their programs are actually
   using terminfo rather than termcap data.

   Still,  there  are a few. A comment about the translation of the ASCII
   NUL character prompted a review:
     * Both   terminfo   and   termcap   store   string  capabilities  as
       NUL-terminated strings.
     * In terminfo, a \0 in a terminal description is stored as \200.
     * There are no (known) terminals which would behave differently when
       sent \0 or \200.
     * When  translating  to  terminfo  format (or displaying a printable
       version of an entry using infocmp), ncurses shows \200 as \0.
     * It has done this since 1998 (quoting from the NEWS file):

[36]980103
...
        + modify _nc_tic_expand() to generate \0 rather than \200.
...
        + correct translation of terminfo "^@", to \200, like \0.

     * However,  the  _nc_tic_expand  function (which optionally produces
       terminfo  or termcap format) did not address this special case for
       termcap.  Even  the  later  4.4BSD  [37]cgetstr  interprets  a  \0
       literally,  ending  that  string  (rather  than using the terminfo
       improvement).

   As  a  result of the review, several improvements were made to ncurses
   translation to/from termcap format -- and improving the checks made in
   tic  for  consistency  of  entries.  Most  of these are not of general
   interest, except for two new command-line options for tic and infocmp:
     * the  "-0"  option  generates  termcap/terminfo  source on a single
       line.
     * the  "-K"  option  provides stricter BSD-compatibility for termcap
       output.

   Other user-visible improvements and new features include:
     * added  "-D"  option  to  tic  and  infocmp,  to  show the database
       locations that it could use.
     * added "-s" option to toe, to sort its output.
     * extended  "-c" and "-n" options of infocmp to allow \ 
comparing more
       than two entries.
     * modified  toe's report when "-a" and "-s" options are \ 
combined, to
       add a column showing which entries belong to a given database.
     * modified  the clear program to take into account the "E3" extended
       capability to clear the terminal's scrollback buffer.

    Examples

   Along  with  the library and utilities, many improvements were made to
   the  [38]ncurses-examples.  Some  were  made  to  allow  building (and
   comparison-testing) against NetBSD curses and PDCurses. Both lack some
   of  the  X/Open Curses features, necessitating customization. But this
   activity  was  useful  because  it  showed  some remaining performance
   issues (which have been resolved in this release).

   These changes were made to verify compatibility or compare performance
   of ncurses:
     * made  workarounds  for compiling test-programs with NetBSD curses,
       though it lacks some common functions such as [39]use_env.
     * added dots_termcap test-program
     * added  dots_curses test-program, for comparison with the low-level
       examples.
     * added   test_setupterm  test-proram  to  demonstrate  normal/error
       returns from the setupterm and restartterm functions.
     * added  "-d",  "-e"  and  "-q"  options  to  \ 
the  demo_terminfo and
       demo_termcap test-programs.
     * added   "-y"   option   to   demo_termcap  and  test/demo_terminfo
       test-programs   to   demonstrate  behavior  with/without  extended
       capabilities.
     * modified  demo_termcap  and  demo_terminfo  test-programs  to make
       their  options  more  directly  comparable, and add "-i" option to
       specify  a  terminal  description  filename  to parse for names to
       lookup.
     * rewrote   the  tests  for  [40]mvderwin  and  test  for  recursive
       [41]mvwin in the movewindow test-program.

   These changes were made to help with the MinGW port:
     * added   test-screens   to   the   ncurses   test-program  to  show
       256-characters at a time, to help with MinGW port.
     * modified the view test-program to load UTF-8 when built with MinGW
       by  using  regular win32 API because the MinGW functions mblen and
       mbtowc do not work.
     * added "-s" option to the view test-program to allow it to start in
       single-step mode, reducing size of trace files when it is used for
       debugging MinGW changes.

   These changes were made to verify new extensions in ncurses:
     * added   [42]form_driver_w   entrypoint   to  wide-character  forms
       library, as well as form_driver_w test-program.
     * modified  ncurses  test-program's  b/B tests to display lines only
       for  the  attributes which a given terminal supports, to make room
       for an italics test.
     * modified  ncurses  test-program,  adding  "-E" and \ 
"-T" options to
       demonstrate use_env versus use_tioctl.
     * modified ncurses test-program's c/C tests to cycle through subsets
       of   the   total   number   of   colors,   to   better  illustrate
       8/16/88/256-colors by providing directly comparable screens.
     * modified the ncurses test-program to also show position reports in
       'a' test.

   These changes were made to make the examples more useful:
     * added scripts for building dpkg and rpm test-packages
     * modified  the  hanoi  test-program  to  show the minimum number of
       moves possible for the given number of tiles.
     * modified  the  knight  test-program  to show the number of choices
       possible for each position in automove option, e.g., to allow user
       to follow Warnsdorff's rule to solve the puzzle.

  Terminal database

   This  release  provides  improvements  to  tic's "-c" checking option,
   which was used for example to
     * make sgr in several entries agree with other caps.
     * correct  padding  in  some  entries  where  earlier  versions  had
       miscounted the number of octal digits.

   There are several new terminal descriptions:
     * [43]mlterm is now aliased to mlterm3
     * [44]nsterm is now derived from nsterm-256color
     * [45]putty-sco
     * [46]teken is FreeBSD's "xterm" console.
     * [47]terminator
     * [48]terminology
     * [49]tmux is derived from screen.
     * several  screen.XXX  entries support the respective variations for
       256 colors.
     * [50]simpleterm is now 0.5
     * [51]vte is aliased to vte-2012
     * [52]vt520ansi

   A few entries use extensions (user-defined terminal capabilities):
     * E3,  used  in  linux,  putty  and  xterm-basic  is  tested  in the
       [53]clear program to erase a terminal's scrollback.
     * TS  is  used  in the [54]xterm+sl building block to help deprecate
       the misuse of tsl for xterm's title-string.
     * XT  is  used  in  some  terminfo entries to improve usefulness for
       other  applications  than screen, which would like to pretend that
       xterm's title is a status-line.
     * xm  is  used  in  examples  [55]xterm-1005  and  [56]xterm-1006 to
       illustrate a way to make mouse handling more general

   A   few   terminals   support  italics  and/or  dim  capabilities.  In
   particular,  screen  does  not.  Documented that, and accommodated the
   terminals where this feature works with the A_ITALIC extension.
     * konsole, mlterm3 (italics)
     * nsterm (dim)
     * screen (dim)
     * vte (dim, italics)
     * xterm (dim, italics)

     * improves documentation by describing new features,
     * attempts  to  improve the description of features which users have
       found confusing
     * fills  in overlooked descriptions of features which were described
       in the [57]NEWS file but treated sketchily in manual pages.

   In  addition,  the  mechanism  for  producing  HTML  versions  of  the
   documentation has been improved:
     * use an improved version of [58]man2html to generate html manpages.
     * regenerated  [59]NCURSES-Programming-HOWTO.html to fix some of the
       broken html emitted by docbook.

  Interesting bug-fixes

     * Ada95 binding:
          + modify  makefile  rules  to ensure that the PIC option is not
            used when building a static library
          + make  Ada95  build-fix  for  big-endian architectures such as
            sparc.  This undoes one of the fixes from [60]20110319, which
            added an "Unused" member to representation clauses, replacing
            that with pragmas to suppress warnings about unused bits.
     * Color and attributes:
          + parenthesize  parameter  of  COLOR_PAIR  and  PAIR_NUMBER  in
            curses.h in case it happens to be a comma-expression.
          + improve  [61]20021221  workaround  for broken acs, handling a
            case  where  that ACS_xxx character is not in the acsc string
            but there is a known wide-character which can be used.
          + modify  [62]init_pair  to  accept  -1's for color value after
            [63]assume_default_colors has been called.
          + add  a  check  in [64]start_color to limit color-pairs to 256
            when extended colors are not supported.
     * Resizing the screen:
          + propagate  error-returns  from  wresize,  i.e.,  the internal
            increase_size    and    decrease_size    functions    through
            [65]resize_term.
          + add  check  for  zero/negative  dimensions for resizeterm and
            resize_term.
          + modify  resizeterm to always push a KEY_RESIZE onto the fifo,
            even  if  screensize  is  unchanged. Modify library to push a
            KEY_RESIZE  if there was a SIGWINCH, even if it does not call
            resizeterm).   These  changes  eliminate  the  case  where  a
            SIGWINCH  is  received,  but  ERR  is returned from wgetch or
            wgetnstr because the screen dimensions did not change.
     * Low-level interfaces
          + fix  an old bug in the termcap emulation; "%i" was ignored in
            tparm  because  the parameters to be incremented were already
            on the internal stack.
          + change  "%l" behavior in tparm to push the string length onto
            the  stack  rather  than saving the formatted length into the
            output buffer.
          + modify  name-comparison  for  tgetstr,  etc.,  to accommodate
            legacy  applications  as well as to improve compatbility with
            BSD 4.2 termcap implementations (see note for [66]980725).
     * High-level interfaces
          + modify internal recursion in wgetch which handles cooked mode
            to  check if the call to wgetnstr returned an error. This can
            happen  when  both nocbreak and nodelay are set, for instance
            (see note for [67]960418).
          + add a check in internal function waddch_nosync to ensure that
            tab characters are treated as control characters; some broken
            locales claim they are printable.
          + modify  menu  library  to  ensure  that  a  menu's top-row is
            adjusted  as needed to ensure that the current item is on the
            screen
          + fix  special  case  where double-width character overwrites a
            single- width character in the first column.

  Configuration changes

    Major changes

   The ncurses 6.0 configure script makes changes to the default value of
   several  configure options, depending on the --with-abi-version option
   (i.e., whether its value is "5" or "6"):

   --enable-const
          Feature  introduced  in  [68]970405  supports  the use of const
          where  X/Open  Curses  should  have, but did not. NetBSD curses
          does something similar with const.

   --enable-ext-colors
          Extends  the  cchar_t structure to allow more than 16 colors to
          be   encoded.   This   applies   only   to  the  wide-character
          (--enable-widec) configuration.

   --enable-ext-mouse
          Modifies  the  encoding  of  mouse state to make room for a 5th
          mouse button. That allows one to use ncurses with a wheel mouse
          with xterm or similar X terminal emulators.

   --enable-ext-putwin
          Modifies  the  file-format  written  by putwin to use printable
          text  rather  than binary files, allowing getwin to read screen
          dumps  written by differently-configured ncurses libraries. The
          extended  getwin  can  still  read binary screen dumps from the
          same  configuration  of  ncurses.  This does not change the ABI
          (the binary interface seen by calling applications).

   --enable-interop
          Modifies  the  FIELDTYPE structure used for the form library to
          make it more generic.

   --enable-lp64
          Allows  an  application  to  define _LP64 to declare chtype and
          mmask_t  as  simply "unsigned" rather than the configured types
          using the --with-chtype and --with-mmask_t options.

   --enable-sp-funcs
          Compile-in support for extended functions which accept a SCREEN
          pointer,  reducing  the  need  for juggling the global SP value
          with [69]set_term and [70]delscreen.

   --with-chtype=uint32_t
          Makes chtype explicitly a 32-bit unsigned value.

   --with-mmask_t=uint32_t
          Makes mmask_t explicitly a 32-bit unsigned value.

   --with-tparm-arg=intptr_t
          X/Open  Curses  declares  [71]tparm  using long for each of the
          parameters  aside  from  the  formatting string, presuming that
          long  and  char*  are the same size. This configure option uses
          intptr_t which provides a better guarantee of the sizes.

   The  configure  script  no longer checks for antique compilers; c89 is
   assumed  as  a  minimum. There are a few features from later revisions
   which  are  used  when available. The configure script makes checks to
   turn on useful warnings from clang, gcc and icc. You should be able to
   build  ncurses  6.0  with  any  of  the  current (or not so current) C
   compilers available in 2015.

   The configure script, by the way, makes changes which do not work with
   systems  whose  /bin/sh is non-POSIX. This mainly affects Solaris (the
   other  vendor  unix systems have followed the POSIX guidelines for the
   past  twenty  years).  If  you  must  build  on  Solaris, its [72]xpg4
   binaries suffice, e.g.,

     #!/bin/sh
     WHAT=`hostname|sed -e 's/\..*//'`
     OUT=configure.out
     cat >>$OUT <<EOF/
     ** `date`
     ** node: $WHAT
     ** user: `id`
     ** conf: $*
     EOF/

     SHELL=/bin/sh
     if test -f /usr/xpg4/bin/sh
     then
             CONFIG_SHELL=/usr/xpg4/bin/sh
             export CONFIG_SHELL
             SHELL=$CONFIG_SHELL
     fi

     rm -f config.status config.cache
     TOP=$HOME/$WHAT
     $SHELL ./configure --verbose \
             --disable-echo \
             --disable-overwrite \
             --enable-warnings \
             --with-warnings \
             --prefix=$TOP $* 2>&1 | tee -a $OUT

   Other major changes to the configure script include:
     * ABI 6 is now the default, intending that the existing ABI 5 should
       build as before using the "--with-abi-version=5" option.
     * added   --with-extra-suffix   option   to   help  with  installing
       nonconflicting  ncurses6  packages,  e.g.,  avoiding  header-  and
       library-conflicts.
       NOTE: as a side-effect, this renames

     adacurses-config to adacurses5-config and
     adacursesw-config to adacursesw5-config
     * the  configure  script  looks  for gnatgcc if the Ada95 binding is
       built,  in  preference  to  the  default  gcc/cc.  The script also
       ensures  that  the  Ada95  binding  is  built  with  the  level of
       optimization as the C libraries.
     * the  configure script captures define's related to -D_XOPEN_SOURCE
       from  the  configure check and adds those to the *-config and *.pc
       files, to simplify use for the wide-character libraries.

Log message:
Changes 5.8:
Interface changes
* turn on _XOPEN_CURSES definition in curses.h.
* change _nc_has_mouse to has_mouse, reflect its use in C++ and Ada95.
* add is_pad and is_subwin functions for opaque access to the WINDOW structure.
* add tiparm, based on review of X/Open Curses Issue 7.

Library Improvements
* add a terminal driver for Windows console, which supports a MinGW port to
  Windows.
* add extended functions which specify the SCREEN pointer for several curses
  functions which use the global SP.
* improve the NCURSES_NO_UTF8_ACS feature by adding a check for an extended
  terminfo capability U8.
* improve performance of tigetstr, etc., by using hashing code from tic.
* add WACS_xxx definitions to wide-character configuration for thick- and
  double-lines.
* modify init_pair to allow caller to create extra color pairs beyond the
  color_pairs limit, which use default colors.

Improvements to Programs
* add tabs program.
* modify tic's -I/-C dump to reformat acsc strings into canonical form (sorted,
  unique mapping).
* add checks in tic for inconsistent cursor-movement controls, and for
  inconsistent printer-controls.
* add special case to _nc_infotocap (used by tic and infocmp) to recognize the
  setaf/setab strings from xterm+256color and xterm+88color, and provide a
  reduced version which works with termcap.

Log message:
ncurses does a bunch of sed magic at *install* time to adjust the
paths in include directives in the headers it installs. (I'm not going
to ask who thought this was a good idea...) Since this package
bypasses the ncurses install goo, we need to replicate at least some
of the behavior with SUBST in order to get working header files out.

Should fix PR 43435 and may also fix some problems with ncursesw and
tin that I've had reported to me.

PKGREVISION -> 4.
