Subject: [PATCH 4/4] ui-diff: add "stat only" diff type
In-Reply-To: <cover.1412502867.git.john@keeping.me.uk>
References: <cover.1412502867.git.john@keeping.me.uk>
Message-ID: <d092ecd33de317c3f680276d3bfad9309d268e1f.1412502867.git.john@keeping.me.uk>

This prints the diffstat but stops before printing (or generating) any
of the body of the diff.

No cgitrc option is added here so that we can wait to see how useful
this is before letting people set it as the default.
