Follow-up Comment #6:

Thanks for the clarification, Bjarni.

Since the patch is not relevant to anyone running groff tools as distributed,
I'm removing the "[PATCH]" indicator.

The one thing this patch does that IMO is worth keeping is commenting the two
empty lines that implement the bug #44714 workaround, especially as that bug
report predicts it will be challenging to fix, suggesting the workaround will
be in place quite a while.  And as I posted over there, the andoc.tmac comment
near the top should cite bug #44714 rather than vaguely referring to "a bug in
GNU troff."  (Or if the two empty lines themselves are given sufficiently
detailed comments, this leading comment may not be needed anymore.)

So I'm altering this bug's Summary to reflect this reduced scope.

As Branden noted in the email thread linked in comment #1, test-nroff is your
own script, not groff's.  (See bug #55941.)
