cua-paste: unexpected behaviour, C-v differs from Edit:Paste

[Stefan Vollmar]

Hello,

I have observed a behaviour in CUA-mode which I find irritating (but I am open 
to the fact that others might prefer this behaviour) and quite sure that I 
could probably adjust it with a suitable setting in my .emacs files (if only I 
knew the magic words).

My problem concerns C-v cua-paste and I was able to reproduce the following 
observations on different X-servers and operating systems (e.g. Ubuntu 10.04 
LTS, Emacs 23.1.50.1):

(1) Copy to clipboard from some application outside of Emacs (e.g. a terminal), 
then C-v in Emacs (when no text selected): text is inserted as expected.

(2) Copy to clipboard from some application outside of Emacs, then C-v in Emacs 
(while some text is selected): will replace selected text with content of 
clipboard - as expected.

(3) Copy to clipboard from some application outside of Emacs, change to Emacs, 
then select text, then click somewhere (selection is no longer highlighted), 
then C-v in Emacs: text is inserted that was previously selected in Emacs - not 
the text I previously copied to the system's clipboard.

(4) If I repeat (3) but use Paste from the Edit menu, I get my preferred 
result: the text copied from the system's clipboard (and not whatever I had 
previously selected and then unselected in Emacs).

At this stage I thought: fine, I just have to configure C-v to execute the same 
command as Paste from the Edit menu. However, I meet the following difficulty 
here: C-h k for both C-v and the Paste menu entry yield very similar 
information - both are bound to cua-paste (although they behave in a subtly 
different fashion).

Many thanks for any help with this.
Warm regards,
 Stefan
