Only the most recent -stable branch is active for ports, i.e. OPENBSD_7_9.
After applying to that tree locally, it builds and "make test" is happy.
Either I can commit (the diff that I have is below, it matches your
-current commit) or you can (cvs co -r OPENBSD_7_9 ports/textproc/groff,
cd, apply, cvs add, commit).
