Merge branch 'mg/gpg-interface-using-status'

Call "gpg" using the right API when validating the signature on
tags.

* mg/gpg-interface-using-status:
pretty: make %GK output the signing key for signed commits
pretty: parse the gpg status lines rather than the output
gpg_interface: allow to request status return
log-tree: rely upon the check in the gpg_interface
gpg-interface: check good signature in a reliable way
