So this is a suggested change to "-p -m" behavior?

Yes, that sounds sane. The current "-p -m" behavior is not useful at all.

So if I understand rightly, we'd have:

 "-p" would be what is currently  "-p --cc"
 "-p -m" would be what is currently "-p --first-parent"
 "-p --no-show-merge-diffs" would be what is currently "-p"

and the rationale would be that

 (a) the current "-p" is hiding things, and while you can add "--cc",
that requires that you really understand what is being hidden, which
is a bad default (the complaint that started this discussion)

 (b) the current "-p -m" is useless crazy stuff, and you'd rather use
it for something that you actually find very common and useful

If so, I agree entirely.
