AFAICT, cua-mode respects shift-select-mode, which makes the menu entry
incorrect.

I tried using this, in emacs -Q:

(progn (setq cua-enable-cua-keys nil)
       (setq shift-select-mode nil)
       (cua-mode 1))

And I did not get "Shift movement mark region".  In fact, the only way
to change that is to set or unset shift-select-mode, with or without
cua-mode.
