It's not been true of the previous ones you've sent me.

A bit of googling suggests git-send-email will do this if it finds a CR
in the patch.  Perhaps that's what happened?

Maybe try sending them one at a time and see if a particular patch is causing
it to happen.  Then play detective on why.

Or just take it as one of those things and ignore it unless it happens again!
