Make Git's gettext messages available to Perl programs through
Locale::Messages. Gracefully fall back to English on systems that
don't contain the module.
This contains some makefile hacks to pass localedir to
perl/Makefile. Which in turn passes it to perl.mak, which'll use it to
search/replace occurances of ++LOCALEDIR++ in .pm files.

+
+=head2 gettext($)
+
+L<Locale::Messages>'s gettext function if all goes well, otherwise our
+passthrough fallback function.
