[PATCH] Built-in diff driver shows Index: line.

From: Junio C Hamano <junkio@cox.net>
Date: Apr 28, 2005, 19:14 UTC
Message-ID: <7vy8b27lyf.fsf@assigned-by-dhcp.cox.net>

As suggested by Linus as a workaround to unconfuse diffstat, this patch adds Index: line before the diff output the built-in driver produces.
