Your tests look good to me. We might want to add some comments for
each test but I guess that can be done before committing. Tomas, it
seems you are planning to push these bug fixes, do let me know if you
want me to take care of these while you focus on the main patch? I
think the first patch needs to be backpatched till 13 and the second
one is for just HEAD.
