Well, it your call: you can disable encryption on the fly by setting the
message to just signing...

I have also found out (to great pains) that it is kind of difficult to
*completely* disable signing or encrypting, as the send-hook will
happily add back the #secure line even if you remove it.

A workaround is to set "mode=none" in the #secure line manually. Maybe
C-c RET C-n could do that instead of just removing the line?

Yes, it is. If force is true, the search-forward will not be ran at
all. The idea here is that if we do not force (ie. if we're running in
the hook), we do not want to override the existing #secure tags, to
respect the users' choices.

Cheers,
