Shouldn't I add it instead of replacing? I followed what I observed in
`git log --grep bbc4d71d63` where all the commits pretty much follow this
pattern: that commit is the one causing the actual observed regression,
while 44a94c7ef989 is much older, and while it's wrong, it wasn't causing
an issue in practice.

Or did I misunderstand something?

Will do.

Not sure I follow you so before I disturb everyone with more noise I'd
just like to confirm: you mean a git send-email in-reply-to=[broken patch
attempt] (the one where I borked the --cc), right? But with what patch?
I'm a bit confused here.

No problem; I really think a scan of all the other boards would be
meaningful though, it looks like a lot of them got fixed but there are
many other candidates and the issue feels pretty critical to me
(regression, and no network at all).
