[PATCH] diff-cache path restriction fix.

From: Junio C Hamano <junkio@cox.net>
Date: May 25, 2005, 00:47 UTC
Message-ID: <7vu0ksrv1v.fsf@assigned-by-dhcp.cox.net>

It advertises the path restriction in documentation and usage string, but the argument parsing code was not updated and was causing it to refuse to run. One liner fix is here.
