Update to 1.12.2.

Changes in version 1.12.2, released on Oktober 5, 2013

 * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
   is now fully functional.
 * The mandoc(1) utility now supports the -Ios (default operating system)
   input option, and the -Tutf8 output mode now actually works.
 * The mandocdb(8) utility no longer truncates existing databases when
   starting to build new ones, but only replaces them when the build
   actually succeeds.
 * The man(7) parser now supports the PD macro (paragraph distance),
   and (for GNU man-ext compatibility only) EX (example block) and EE
   (example end).  Plus several bugfixes regarding indentation, line
   breaks, and vertical spacing, and regarding RS following TP.
 * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
   the \z (zero cursor advance) escape and the cc (change control
   character) and it (input line trap) requests. Plus bugfixes regarding
   the \t (tab) escape, nested escape sequences, and conditional requests.
 * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
   enclosures, delimiter handling, list indentation and horizontal and
   vertical spacing, formatting of the Lk, %U, and %C macros, plus some
   bugfixes related to the handling of syntax errors like badly nested
   font blocks, stray Ta macros outside column lists, unterminated It Xo
   blocks, and non-text children of Nm blocks.
 * In tbl(7), the width of horizontal spans and the vertical spacing
   around tables was corrected, and in man(7) files, a crash was fixed
   that was triggered by some particular unclosed T{ macros.
 * For mandoc developers, we now provide a tbl(3) library manual and
   gmdiff, a very small, very simplistic groff-versus-mandoc output
   comparison tool.
 * Provide a NEWS file.

Changes in version 1.12.1, released on March 23, 2012

 * Significant work on apropos(1) and mandocdb(8). These tools are now
   much more robust.  A whatis(1) implementation is now handled as an
   apropos(1) mode.  These tools are also able to minimally handle
   pre-formatted pages, that is, those already formatted by another
   utility such as GNU troff.
 * The man.cgi(7) script is also now available for wider testing.
   It interfaces with mandocdb(8) manuals cached by catman(8).
   HTML output is generated on-the-fly by libmandoc or internal
   methods to convert pre-formatted pages.
 * The mailing list archive for the discuss and tech lists are being
   hosted by Gmane at gmane.comp.tools.mdocml.user and
   gmane.comp.tools.mdocml.devel, respectively.
