With that additional rule, I can buy "it is fine for 'git cp --help'
to completely ignore -n and behave as if 'git help cherry-pick' was
given", I think. People already expect "git cp --help" to give the
alias expansion, so to them any change will be a regression any way
we cut it---but I think this is the least bad approach.

One very good thing about the "make '--help' go directly to the
manpage, while teaching '-h' to report also alias expansion" is that
people already expect "-h" is more concise than "--help". The
current output from "git cp --help" violates that expectation, and
the change you suggest rectifies it.

Yeah, but that is not an argument. The user aliased cp because
cherry-pick was quite a mouthful and do not want to type "git
cherry-pick --help" in the first place.
