If we were designing this function now, then being stricter here would
be a good idea.  But if there's code out there that relies on the
current sloppy parsing, then it'd be problematic to make it stricter.

On the other hand, I think that function was introduced in emacs-28, so
perhaps that's not a concern in practice?
