According to RFC1341, the multipart boundary indicated by the
Content-Type header must be prepended by CRLF + "--", and followed
by CRLF. In the case of strict MIME header boundary handling, the
"--" was forgotten to add.

Fixes trac #7921.

D'uh, I told git send-email that the subject should contain "V2". I
wonder why that gets ignored.
