From: Junio C Hamano Date: Fri, 27 Oct 2006 21:08:14 +0000 (-0700) Subject: merge-recursive: adjust to loosened "working file clobbered" check X-Git-Tag: v1.4.4-rc1~4^2~1 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=65ac6e9;p=git.git merge-recursive: adjust to loosened "working file clobbered" check The three-way merge by git-read-tree does not complain about presense of the file in the working tree that is involved in a merge when the merge result needs to be determined by the caller. Adjust merge-recursive so that it makes sure that an untracked file is not touched when the merge decides the path should not be included in the final result.
