From 52be5fcd29e074cb549b9a92ff8caceb736e4851 Mon Sep 17 00:00:00 2001
From: Junio C Hamano <junkio@cox.net>
Date: Sun, 4 Sep 2005 15:40:18 -0700
Subject: Add copy/rename check for git-apply.

The new test pattern is taken from HPA's klibc and klibc-kbuild trees,
which has many interesting renames (the commits
001eef5a19219e5b0601068a3d13874b88c0653e and
0037d1bc0deaf7daec3778496656cb04b4e4b9d0).  The test pattern exposes
problems in the apply.c changes currently in the proposed updates
branch.
