Update to 1.12.0:

08-10-2011: version 1.12.0

This version features a new, work-in-progress mandoc output mode:
-Tman. This mode allows a system maintainer to distribute man media
for older systems that may not natively support mdoc, such as old
Solaris systems. The -Ofragment option was added to mandoc's -Thtml
and -Txhtml modes.

While adding features, an apropos utility has been merged from the
mandoc-tools sandbox. This interfaces with mandocdb for semantic
search of manual content. apropos is different from the traditional
apropos primarily in allowing keyword search (such as for functions,
utilities, etc.) and regular expressions. Note that the calling
syntax for apropos is likely to change as it settles down.

In documentation news, the mdoc and man manuals have been made
considerably more readable by adding MACRO OVERVIEW sections, by
moving the gory details of the LANGUAGE SYNTAX to the roff manual,
and by moving the very technical MACRO SYNTAX sections down to the
bottom of the page.

Furthermore, for tbl, the -Tascii mode horizontal spacing of tables
was rewritten completely. It is now compatible with groff, both
with and without frames and rulers. Nesting of indented blocks is
now supported in man, and several bugs were fixed regarding
indentation and alignment. The page headers in mdoc are now nicer
for very long titles.
