I'm investigating this. Thanks for the report!

Well, 46b402a0e5e4 refers to version 6 of my patchset and 563558b2c735
is a diff between version 6 and 7. I've seen from the e-mails from
Andrew that I received that he added both patches and then folded the
latter into the former. The same thing happened with several other
patches but only these two sneaked in. Maybe this is a bug in the
software (quilt?).
