Subject: [PATCH] * (mime-add-application/pgp-keys): Use
 `mime-insert-entity-content' and `mime-pgp-detect-version'
 to get public keys.
 (mime-decrypt-application/pgp-encrypted): Use
 `mime-entity-detect-pgp-version' instead of
 `mime-pgp-detect-version'.
 (mime-verify-application/pgp-signature): Likewise.
 (mime-entity-detect-pgp-version): Function to detect PGP
 version from entity content; renamed from
 `mime-pgp-detect-version'. (mime-pgp-detect-version): New
 function to detect PGP version in the buffer.
