in repository groff.
commit cebfa10c6a6fbd1b7e7269b7760551078a34c307
Author: G. Branden Robinson <[email protected]>
AuthorDate: Sun Jul 5 20:19:55 2026 -0500
[groff]: Add unit test for `fzoom` request.
* src/roff/groff/tests/fzoom-request-works.sh: Do it.
* src/roff/groff/groff.am (groff_TESTS): Run test.
Test script based on log of commit f03e6f62e1, 2023-08-04--thus the
copyright year range. (One could argue thresholds; see our "HACKING"
file. I'm up for the armchair lawyering if you are!)
