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. > $ git cp --help > > I.e., you already know the "-n" part, and now you want to dig further. 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. > Of course one could just type "git cherry-pick --help" since you also > know that, too. 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.
