From: Junio C Hamano Date: Wed, 27 Apr 2005 16:21:00 +0000 (-0700) Subject: [PATCH] Add -p (patch) to diff-tree. X-Git-Tag: v0.99~727 X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=3ebfd4aa29e30187ad7a3f75fa2d2971878468e7;p=git.git [PATCH] Add -p (patch) to diff-tree. This uses the reworked diff interface to generate patches directly out of diff-tree when -p is specified.
