Subject: [PATCH v5 27/44] builtin-am: implement --[no-]scissors
Date: Tue,  7 Jul 2015 22:20:45 +0800	[thread overview]
Message-ID: <1436278862-2638-28-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1436278862-2638-1-git-send-email-pyokagan@gmail.com>

Since 017678b (am/mailinfo: Disable scissors processing by default,
2009-08-26), git-am supported the --[no-]scissors option, passing it to
git-mailinfo.

Re-implement support for this option in builtin/am.c.

Since the default setting of --scissors in git-mailinfo can be
configured with mailinfo.scissors (and perhaps through other settings in
the future), to be safe we make an explicit distinction between
SCISSORS_UNSET, SCISSORS_TRUE and SCISSORS_FALSE.

Signed-off-by: Paul Tan <pyokagan@gmail.com>

Notes:
    v5
    
    * Previously, SCISSORS_FALSE was 1 while SCISSORS_TRUE was 0. This
      should be the other way around.
