fix(man): Finding git man page link opportunities

When finding opportunities to create links to git man pages, text of the
form "... git-command(1)." or "... git-command(1)," were missed because of
the trailing punctuation. These cases are now accounted for correctly.

N.B. this repair does not currently affect any generated documents.
