This is no longer done, but it's still not quite right.
If you do:
(local-set-key [(meta z)] 'execute-extended-command)
Then you still get "M-x" as the prompt if you do `M-z'.
The reason is that it looks up the command first, and then picks one of
the bindings as the description, with code that's kinda like this:
(key-description (car (where-is-internal 'execute-extended-command)))
Is there any reason it doesn't just use this_command_keys which
presumably would be more correct?
