Thanks, this is amazingly more simple than what I had. This works
fine but I'm looking at the code for cmd and don't really see how you
get completion to work on the new alias.

Also, I would like the alias to have arguments:

alias newName existingName arg1 arg2 ...

Currying comes to mind, but I haven't tried it yet. Thanks again for
the help.
