making sudo work with functions/builtins

[Sweth Chandramouli <sweth@astaroth.nit.gwu.edu>]

	a while ago, someone asked about how to deal with the following 
sort of situation:

% alias mv='nocorrect mv'
% alias sudo='sudo '
% sudo mv foo bar
sudo: nocorrect: command not found

	from what i can tell, this happens because sudo requires that its 
first argument be an actual command, and not a builtin or a function; 
adding the space after sudo in the alias makes expansion take place on cp,
so that what sudo sees as the first arg is 'nocorrect'.  i just had a
little brainstorm about how to get around this:

% alias mv='nocorrect mv'
% ls
cmd foo
% alias sudo='sudo cmd '
% cat cmd
#!/bin/sh
eval $SHELL -c \"$@\"
% sudo mv foo bar
% ls
bar cmd
%

	my question is twofold--is there a more efficient way to do
this, and can anyone see a situation where this would break something
that would otherwise work?
