Subject: * pgg-pgp.el (lookup-key-string): Use `call-process' instead of
X-Git-Tag: emiko-1_13_7~65
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=015801b03b9f7a84d860212b2de0975c3978e4f7;p=elisp%2Fsemi.git

* pgg-pgp.el (lookup-key-string): Use `call-process' instead of
`pgg-pgp-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'.
