The notmuch reply command structured output formats contain the original
message, with all the information needed to determine whether the
message was signed and/or encrypted. Someone(tm) just needs to write the
code to check that in emacs (probably fits in the quoting loop), and
insert the appropriate mml tag (or whatever it's called) to tell message
mode to encrypt.
