Mouse interaction in -nw

[Ergus]

Hi:

I have been noticing some recent issue in xterm-mouse-mode not sure if
they are issues or features.

1) emacs -Q -nw
2) M-x xterm-mouse-mode
3) Select a region (like the word "buffer" in the scratch) with the mouse
4) M-w

5) Try to paste the word anywhere

In my system it seems that the mouse highlights the region properly,
but never moves the mark. So after M-w it copies the region between
point and original mark position not the selected word.

Is this intended? Because in gui this works "as expected"

Best,
Ergus
