That's not really true, as I deliberately did the split_cmdline after
printing the "is an alias for", but before "continuing to help for", so
this would precisely tell you
cp is an alias for 'cherry-pick -n'
continuing to help for 'cherry-pick' in 1.5 seconds

No, in that case I would not expect git cp --help to jump to that
section anymore than I would expect "git cherry-pick -n --help" to
magically do that (and that would be impossible in general, if more
options are bundled in the alias).

I considered that, and could certainly live with that. But it seems the
discussion took a different turn in another part of the thread, so I'll
continue there.
