Great, I haven't yet included b4 in my workflow so, to be honest, I didn't
really thought about that tool being confused.  What really made me resend
the patch was that I used the *wrong message-ID in the "--in-reply-to"!
And that thread already had a v2 patch, which would could easily confuse
humans.  Hopefully, b4 won't be confused by that either.
