Luc, thanks for the precise analysis!!

Yes, cua-mode relies on transient-mark-mode to highlight the selected
region, but since it uses other methods to highlight a selected
rectangle, it needs to turn off transient-mark-mode temporarily when
it highlights a rectangle.  That is why it automatically turns it
(back) on when no rectangle is selected.

There is no option to disable transient-mark-mode completely with cua,
but isn't cua-highlight-region-shift-only sufficient?

Of course, cua could turn on transient-mark-mode just in case
mark-active is t, but that wouldn't make any difference, as
transient-mark-mode is only looked at when mark-active is t.

BTW, the code in question hasn't changed since 2002, so I'm puzzled
why you think this is a new "problem"!?
