Subject: [PATCH v6 06/11] ref-filter: implement '--merged' and '--no-merged' options
Date: Thu, 25 Jun 2015 14:27:08 +0530 [thread overview]
Message-ID: <1435222633-32007-6-git-send-email-karthik.188@gmail.com> (raw)
In-Reply-To: <1435222633-32007-1-git-send-email-karthik.188@gmail.com>
In 'branch -l' we have '--merged' option which only lists refs (branches)
merged into the named commit and '--no-merged' option which only lists
refs (branches) not merged into the named commit. Implement these two
options in ref-filter.{c,h} so that other commands can benefit from this.
