Log Message:
Update to 6.5

Changelog:
6.5 (12 September 2017)
* info:
  . some bugs fixed:
    . a bug where a segfault could happen in the regex search, for
      example when the user entered a single \ as the search string
    . another bug which could make nodes inaccessible in long "split"
      info files
    . a bug where it was not possible to follow a cross-reference
      that was split across more than one line has been fixed
  . do not fall back to a man page if following a cross-reference in an
    info file failed
  . if looking for a file failed, do not convert the name of a file to
    lower-case and look for it again

* texinfo.tex
  . some faulty definitions for Unicode characters have been changed or
    removed
  . fix indentation in table of contents for entries that are split
    across multiple lines

* texi2dvi
  . a bug that broke the processing of LaTeX files that did not
    use BibTeX has been fixed

* texi2any
  . output the encoding declaration of a HTML file earlier so it
    will always occur within first 1024 bytes of file
  . `INLINE_INSERTCOPYING' removed as a customization variable

6.4 (23 June 2017)
* texi2any:
  . for HTML output, place section names before the manual in page
    titles, instead of after them, so it is easier to distinguish pages
    if titles are truncated
  . starting points for ordered lists beginning with 0 or a letter of
    the alphabet are output as attributes on the <ol> tag, as was
    case for Texinfo 4.13 and earlier
  . a bit faster
  . some discrepancies in paragraph formatting between Perl extension
    modules and interpreted Perl modules have been fixed
  . `MACRO_BODY_IGNORES_LEADING_SPACE' customization variable removed,
    and `indent_menu_descriptions' is no longer a possible value for
    `TREE_TRANSFORMATIONS' (as these features did not work as
    documented)

* info:
  . the `up-line' and `down-line' commands now are like the other
    scrolling commands and are no longer confined to a single node
    (depending on the value of `scroll-behaviour')
  . supplying the --all option with --index-search displays a list
    of matching index entries
  . the style variables like `link-style' can now be set while info
    is running
  . display bug fixed where color could be turned off prematurely
  . several other bugs fixed
  . better portability in test suite
  . do not fall back to showing the dir node if a manual isn't found
  . Do not attempt any kind of conversion of CR LF line endings,
    except on MS-DOS/Windows, when it is done unconditionally.  (This
    replaces a more complicated approach, where this conversion would
    take place if there was a problem finding a node in a file.)  The
    main effect of this change is that Info files with CR LF line
    endings, which would have been produced on MS-DOS/Windows with old
    versions of makeinfo, are only supported on such operating systems.
  . a few of the key bindings under --vi-keys have been changed for
    consistency or to match the documentation

* texinfo.tex
  . a DVI file with a single empty page can be output again, which
    restores the behavior from Texinfo 6.0 and earlier

* Distribution
  . autoconf 2.69, automake 1.15, gettext 0.19.8
