[PATCH] pull: use merge-base --fork-point when appropriate

From: John Keeping <john@keeping.me.uk>
Date: Dec 8, 2013, 12:47 UTC
Message-ID: <b208a2edcaf47bf1a97ec19718854dc1b3646828.1386506845.git.john@keeping.me.uk>

Since commit d96855f (merge-base: teach "--fork-point" mode, 2013-10-23) we can replace a shell loop in git-pull with a single call to git-merge-base. So let's do so.
