Comment:
Patch applies against 5.0.beta8 (and 4.8) and runs; fixes the OP's
symptom; has a doctest; doesn't introduce new doctest failures (I have
quite a few on beta8 but they came before, and it works cleanly against
4.8); and it's clear what the bug was and why this patch fixes it.
Positive review.
