Re: should xterm-mouse-mode be on by default?

[Richard Stallman]

    Because the a selection done with the mouse when xterm-mouse-mode is
    active is not available to X. It is only available to Emacs, so it is
    possible to use the mouse to copy between 2 emacs windows running in
    the same terminal frame, but X know nothing about the selection. 

I did not realize it had this disadvantage.  It is a serious one.

I think we should put the default back to off.
