[PATCH v2 1/5] gpg-interface, tag: add GPG_VERIFY_QUIET flag

From: santiago@nyu.edu <santiago@nyu.edu>

Message-ID: <20160926224233.32702-2-santiago@nyu.edu>
In-Reply-To: <20160926224233.32702-1-santiago@nyu.edu>

From: Lukas P <luk.puehringer@gmail.com>

Functions that print git object information may require that the gpg-interface functions be silent. Add GPG_VERIFY_QUIET flag and prevent print_signature_buffer from being called if flag is set.
