I'm afraid this issue is left up in the air after application of the
fix-up patch, as usage of --cc in the diff-index is still undocumented.
I.e., the fix-up just restores the historical status quo that has a
problem by itself.

As current documentation of --cc elsewhere does not seem to be even
suitable for diff-index, I don't feel like providing corresponding patch
for the documentation, even less so as I still have no idea if current
behavior is intended or accidental, and if it's the latter, do we need
to keep or somehow fix it? Anybody?
