Few tiny comments.
Thanks for the patches.

You changed the output slightly. The original awk script outputed:

the first line of the commit message
From: foo@....
remainder of the commit message
<<<<<
Yours outputs:
>>>>>
From: foo@....
the entire commit message
<<<<<
I'd like to keep the previous format as it makes it easier to grab the first
line of each patch file to get the "short summary" (assuming you follow the
kernel/git/guilt commit message conventions). This doesn't make anything in
guilt easier, it just makes the patch files more friendly to other tools one
might use. (Especially if they grab the first line and use it as the subject
in emails.)

Shouldn't that be '"$series" > "$series.tmp"' ?

.new or .tmp?
