From: Junio C Hamano Date: Wed, 29 Nov 2006 20:07:37 +0000 (-0800) Subject: merge-recursive: use xdl_merge(). X-Git-Tag: v1.5.0-rc0~127^2~8 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c2b4faea4522b28a7611ddab5eb6a5c221cc3ee5;p=git.git merge-recursive: use xdl_merge(). This seem to pass the existing tests already.
