I got tired of "cvs diff" always reporting one-line changes in man pages
due to time stamps, so I added the following hack to avoid generating new
man pages simply because the month has changed.

* man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
(.x.1): Ignore the time stamp in the .TH line when deciding whether
to update the man page. That way, we don't have to check in new
man pages every month.
