git-apply doesn't apply the commit message. git-am is what you want. It 
tripped up my scripts, but that seems to because it has line-feed char 
in Message-ID. It did apply manually running b4.

There's a b4 relay you can use to send if you can't get SMTP to work. 
Messing with things manually is asking for trouble.
