Stefan Kangas suggested I resend this patch to this mailing list so that
it's not lost even though it can't be applied yet.

Just to clarify for posterity: it can't be applied yet because 
list-of-string-p is not in Emacs 26. Or 27 (which we might bump the 
requirement to in not-too-distant future).

Right.  Note that `list-of-strings-p' was added in Emacs 28, though.
So I added a comment to that effect in commit 9647ddb2993, and I'm
closing the bug.

I think you meant to say Emacs 29 here.
