[MAINTAINER UPDATE] textproc/lowdown to 1.1.2

This is a maintainer update for textproc/lowdown to 1.1.2. The changes
for 1.1.1 and 1.1.2 are:

"Add documentation for --html-titleblock and slightly change semantics
where it will print regardless if in -s mode.

Add regression code coverage to main website, include make rules for
generating coverage. Many more regression tests to exercise coverage.

Fix UTF8 handling on Mac OS X. Prior to this, some UTF8 characters (such
as smart punctuation) were being garbled on -Tgemini and -Tterm output.
These now render properly thanks to an excellent pull request
contribution (#140).

Hack around more buggy Mac OS X software,
specifically their version of makewhatis(8). While man(7) specifically
allows for header macros (SH) to have their contents on the subsequent
line, this breaks buggy software that erroneously expects headers to
have their content on the same line. This version, thanks to another
excellent pull request (#138), adds a hack for that specific condition."

I don't believe these changes warrant a SHARED_LIBS bump but I could be
wrong. Everything seems to work fine from my testing.
