include the sender's own public key as part of a 
detached OpenPGP signature?

=====
Possible, but slightly tedious:

[1] Export the public key as an asc file
[2] Add a line after the last line, saying that the key as well as
whatever is to be signed in the message is now being signed by the
signer's key (list name and long fingerprint
[3] Armor sign the entire thing  (asc key file and extra line)
[4] Send the Armored signed message as the attachment instead of the
signature
