From: Junio C Hamano Date: Sun, 22 May 2005 02:40:36 +0000 (-0700) Subject: [PATCH] Prepare diffcore interface for diff-tree header supression. X-Git-Tag: v0.99~508 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=38c6f78059c3060db6f94b24f4a90063a91090d2;p=git.git [PATCH] Prepare diffcore interface for diff-tree header supression. This does not actually supress the extra headers when pickaxe is used, but prepares enough support for diff-tree to implement it.
