It has cua-set-rectangle-mark, other than that it only seems to make
some relatively minor adjustments to behavior.

  `cua-mode' Minor Mode Bindings:
  key             binding
  ---             -------

  C-S-SPC		cua-toggle-global-mark
  <C-return>	cua-set-rectangle-mark
  <remap>		Prefix Command

  <remap> <clipboard-yank>	cua-paste
  <remap> <exchange-point-and-mark>
  				cua-exchange-point-and-mark
  <remap> <scroll-down>		cua-scroll-down
  <remap> <scroll-down-command>	cua-scroll-down
  <remap> <scroll-up>		cua-scroll-up
  <remap> <scroll-up-command>	cua-scroll-up
  <remap> <set-mark-command>	cua-set-mark
  <remap> <x-clipboard-yank>	cua-paste
  <remap> <yank>			cua-paste
  <remap> <yank-pop>		cua-paste-pop

So I'm not sure how to summarize this.

My proposal is to name the menu item "CUA Mode (without C-x/C-c/C-v)"
and the tooltip "Enable CUA Mode without setting C-x/C-c/C-v keys".  Not
sure that the proposal is very good, but it's what I can think of.  At
the very least it's better than the incorrect text we have now.
