That makes sense when parsing trailers out of "format-patch" output, but not when we know we have just the commit message. So one obvious fix is a new option for the trailer code to tell it we have _just_ a commit message. That would still leave this obvious false positive for the format-patch case, but I'm not sure it can be helped. -Peff
