Not really.  This is a suggested behaviour for "git log -p"; I
wasn't very enthused by the idea to turn --cc when user said -p
without telling them what we are doing.  In other words, if the
users want combined, they should say --cc (and they will get a
single-parent patch for non-merges with --cc) so there is no reason
not to do this, as long as we fix --cc so that "git log --cc"
implies "git log --cc -p".

Not really.

Not really.  I was dropping "-m" entirely with "we could do -p -m2
but I do not think we should bother".

Yes.
