That looks like it probably ought to be regarded as a bug to me, yes ---
I guess it's been hidden because the test "if this statement successfully
jumped somewhere completely different then..." isn't spectacularly useful.
However, it's not logically wrong, either.

I think we had something a little similar to this recently; it usually
boils down to something quite simple once you've found it and I'll
have a look when I've got more time.  (Patch would go to zsh-workers.)
