BTW. the series went a bit out of whack, I suspect because of an older
iteration of patches leftover from a previous git format-patch, then
git send-email *.patch picks up some of the old patches if they were
renamed or reordered.

Don't worry this has bitten me before. Would be nice if send-email had
some heuristic to sanity check metadata in cover letter and subject
lines to warn about this...

I think I've been able to untangle it.

Thanks,
