commit d8641e9e355f2e2b55c01bf376ed59cda097efe0
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sun Sep 1 23:58:00 2024 -0500

    [groff]: Update code style of test.
    
    * src/roff/groff/tests/dot-cp_register_works.sh: Migrate to more recent
      test conventions.  Use `fail` variable and `wail()` function instead
      of `set -e`.  Report more status.  Add Vim modeline.
