Subject: [PATCH] * pgg-pgp5.el (lookup-key-string): Use `call-process'
 instead of `pgg-pgp5-process-region'. (encrypt-region): Use
 `pgg-process-when-success'; if the output buffer is empty,
 don't copy errors, just return nil. (decrypt-region):
 Likewise. (verify-region): Likewise. (sign-region): Accept
 optional argument `clearsign'.
