Re: [PATCH] diff: squelch empty diffs even more

When we compare two non-tracked files or explicitly specify
--no-index then the suggestion to run git-status is not helpful.

That observation is correct but how does skip_stat_unmatch count
up in such a case?  Shouldn't diffcore_skip_stat_unmatch()
function be taught about such a "fake" filepair that did not
come from git, and ignore the stat differences?
