OK, so I get clearly no partial PGP messages and no using rfc3516
formatted pgp mail.

But this doesn't help with what practise you want us to follow. Do you
want us to send full signed email using pgp encapsulation for pull
requests in spite of the mangling it does to attached patches and the
amount of extra pain it causes you? Or is relying on looking at the
received headers and always using public email lists to detect spoofing
by revocation OK until we find a mechanism for integrating pgp into git?
