Re: diff-index --cc no longer permitted, gitk is now broken (slightly)

Sorry for the delay; I did not notice there was a patch buried in a discussion thread.

We might later need to do this suppression in more codepaths if we find more regressions, but let's have one fix at a time.

Will queue.

This would deserve new tests that cover the existing use cases, given that both of us (and other reviewers in the original thread) did not notice how big a regression we are causing.

We care about --cc naturally falling back to -p when there is only one other thing to compare with, and also we care about --cc that allows us to compare during conflict resolution, at least, I think.

It can and should come as a separate step, of course. Unbreaking gitk for an already known breakage would be more urgent than hunting for other breakages, even though the latter might result in a more thorough fix in the end.

Thanks.
