Subject: [PATCH (GITK) 4/6] gitk: Fixed broken exception handling in diff.
Message-ID: <200807271020.53171.angavrilov@gmail.com>
In-Reply-To: <200807271020.02415.angavrilov@gmail.com>

If the tree diff command failed to start for some
random reason, treepending remained set, and thus
no more diffs were shown after that.
