From 939aabbf7d108b5d6830bf5cd89abc910cc9ff27 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 28 Jan 2006 02:09:08 -0800 Subject: [PATCH] diff-files -c/--cc: combine only when both ours and theirs exist. The previous round forgot to make sure there actually are two versions to compare against the working tree version. Otherwise using -c/--cc would not make much sense. Also plug a small memory leak.
