Subject: [PATCH 5/9] Teach git var about GIT_PAGER
Date: Wed, 11 Nov 2009 18:02:09 -0600 [thread overview]
Message-ID: <20091112000208.GF1140@progeny.tock> (raw)
In-Reply-To: <20091111235100.GA1140@progeny.tock>
Expose the command found by setup_pager() for scripts to use.
Scripts can use this to avoid repeating the logic to look for a
proper pager in each command.
