[G. Branden Robinson]

Follow-up Comment #4, bug #51482 (project groff):

We've changed course on this per recent discussion on the groff mailing list.

    test-groff.in: Stop passing groff -b and -ww.
    
    * test-groff.in: Stop passing the built groff executable -b and -ww
      options by default.  This reverses a change from 2017.  Dave Kemper
      has convincingly argued that there's no way to override -b and turn
      backtraces on warnings/errors back off, and that the built groff
      should behave as much like a "normal" one as possible.  The latter
      factor is of added importance now that we are using test-groff for
      generation of documents.
    
    * src/roff/groff/tests/regression_savannah_58153.sh: Adapt.
    
    If you're a bleeding edge groff user who runs it straight from
    build trees, I recommend writing shell aliases or functions to
    capture the desired behavior.
    
            alias tg='./build/test-groff -b -ww'
            alias tgu='./build/test-groff -b -ww -Tutf8'
