Done. :-)

Now you should get one single e-mail when your bug fix is
cherry-picked, as both changes are committed together (the comment
addition and the bug removal from the blocking list).

Naturally, if you watch the meta-bug as well, you'll get an additional
e-mail showing that your bug has been removed from its blocking list.
There's nothing I can do about that (it's an informative e-mail for
everybody else, after all).
