This requires that the conflicting files are named identically.  The
problem with CUA is that the old and new files have different names,
and the file name has actually changed three times, so this is
unfortunately not a viable option for CUA.

Also, the shadowing may easily be introduced later if the user
modifies the load-path in his own .emacs file.

That only works if all existing users have installed the old cua
package in those directories (provided they exist).  Not something
I would rely on.

I now have a pretty good working solution for CUA based on
eval-after-load.  I'll install it shortly.
