mandoc: update to 1.14.5.

i just released mandoc-1.14.5.  This is a regular maintenance
release.  As structural changes are quite limited, i expect it to
be very stable, so all downstream systems are encouraged to upgrade
from any earlier version.

New features include:

 * The apropos(1) utility now accepts case-insensitive extended
   regular expressions by default, improving POSIX compliance
   (thanks to Wolfram Schneider for the suggestion).
 * The new man(1) -O tag[=term] output option opens a page at the
   definition of a term (thanks to Klemens Nanni for the suggestion).
 * The output from tbl(7) has been significantly improved in both
   the HTML and the UTF-8 output modes (thanks to Pali Rohar for
   many reports and suggestions).
 * Several syntax errors have been fixed in HTML output and the
   HTML output code quality has been further improved, in particular
   with respect to paragraphs, tagged lists, and tooltips
   (thanks to John Gardner for significant help).
 * Low-level roff(7) support has been further improved such that
   mandoc can now handle the manual pages of the groff package.
 * Many bugs have been fixed.
