See below, although I won't be pulling this but applying the patches.

I've also attached my skanky get-msgid script which I use when
committing as:

~/get-msgid -g '1 8' 
'<1395068010-23344-1-git-send-email-ian.campbell@xxxxxxxxxx>' | git am

(-g is "git send email the following range, per seq(1)")
Ian.
