Yeah, I'd agree with this. My feeling is that when there are two
options, A and B, and A is a no-op if B is not also specified, that it
makes sense for A to imply B. We do it in several places already (and I
just added some for "git branch --list" recently).
Is "--cc" a no-op when "-p" is not specified? Certainly "-c" is not, but
I do not think you are proposing that. At first glance, "--cc" is
nonsensical without "-p", but what about other xdiff callers? For
git log --cc --stat
the "--cc" is significant. So I don't think it is right for "--cc" to
always imply "-p". But if the rule kicked in only when no other format
had been specified, that might make sense.
