in repository groff.

commit 8f7aba07ae7844f6667fd91475cefd45f868d725
Author: G. Branden Robinson <g.branden.robin...@gmail.com>
AuthorDate: Tue Aug 5 07:17:25 2025 -0500

    [mm]: Improve test scripts (1/3).
    
    * contrib/mm/tests/short-pages-do-not-overflow-stack.sh:
      - Add "nl -ba" to output pipeline for easy line counting by humans.
      - Make test stricter by expecting specific line counts instead of
        merely a successful exit status.
      - Emit the formatted document to the standard output for easy review.
    
    Also update copyright notice.  I've never executed copyright assignment
    paperwork with the FSF, so my contribution of this script can't be under
    the FSF's copyright.
    
    Also drop empty comment stump at end of comment block.
    
    Also make Vim modeline more human-readable.
