Package: emacs,gnus
Version: 30.1

I'm running emacs 30.1 on debian.  When sending cleartext mail, i want
to be able to produce an "Unobtrusive Signature" using OpenPGP as
described in
https://datatracker.ietf.org/doc/draft-gallagher-email-unobtrusive-signatures/

Those kinds of signatures provide end-to-end cryptographic protection
for headers (based on
https://datatracker.ietf.org/doc/draft-ietf-lamps-header-protection/ )
as well as the message body, and are less likely to inflict bad UX or
bad rendering on recipients using legacy MUAs compared to PGP/MIME (or
inline PGP, for that matter).

These three patches appear to do the trick for me.  I'm not an elisp
guru or a gnus expert.  I'm happy to hear any feedback about how they
could be improved.

Regards,
