Add a cross reference to patch(1)

as suggested by Thomas de Grivel <billitch at gmail dot com> on tech@.
While here, remove the SEE ALSO entries (but not the cross references
at the appropriate places!) to fnmatch(3), re_format(7), and pr(1).
Their relevance is restricted to one single option each, the latter
is mostly obsolete nowadays anyway, and the number of SEE ALSO entries
is so large that SEE ALSO is starting to look confusing.
