That’s a very good point. I didn’t consider aliases and hooks.
My use case is for building on top of existing commands so they can
be extended/tweaked. Aliases and hooks need to follow the new
command, including the ones set by users (so I have no way of knowing
about them).
I can’t think of any way of making a rename command work like this.
Any idea? Otherwise, would my original patch be acceptable if I
changed the name from up level and only use relative levels?
