X-Git-Tag: v1.4.3-rc1~128^2 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=cb2b9f5ee15547e878c668504140c66f3a42d81c;p=git.git diff-index --cc shows a 3-way diff between HEAD, index and working tree. This implements a 3-way diff between the HEAD commit, the state in the index, and the working directory. This is like the n-way diff for a merge, and uses much of the same code. It is invoked with the -c flag to git-diff-index, which it already accepted and did nothing with.
