Subject: [PATCH v4 26/44] builtin-am: support --keep-cr, am.keepcr
Date: Sun, 28 Jun 2015 22:05:48 +0800	[thread overview]
Message-ID: <1435500366-31700-27-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1435500366-31700-1-git-send-email-pyokagan@gmail.com>

Since ad2c928 (git-am: Add command line parameter `--keep-cr` passing it
to git-mailsplit, 2010-02-27), git-am.sh supported the --keep-cr option
and would pass it to git-mailsplit.

Since e80d4cb (git-am: Add am.keepcr and --no-keep-cr to override it,
2010-02-27), git-am.sh supported the am.keepcr config setting, which
controls whether --keep-cr is on by default.

Re-implement the above in builtin/am.c.
