Fix and clean up -t flag:

 - Add comments.
 - Support -t-inline-comments-like-man-page-says.
 - -tfilename still works.
 - When using -t (read description from stdin) don't end when first
   character is `.'.  Instead, end if whole line consists of one `.'.
 - Add regression test.

I also changed the regression Makefile to have a trailing slash on
the final element.  As long as we have a blank line it will be fine,
plus it will save us some trouble when adding new tests.

After adding line breaks, ``rest looks fine.'' xsa@
