Subject: [patch] avoid.el - keep mouse pointer within the same window
Sender: emacs-pretest-bug-bounces+rms=gnu.org@gnu.org
Hi.
The following patch (excuse my lisp) keeps the mouse pointer within the
same window when mouse avoidance mode decides to move it away. Helps
with mouse-autoselect-window turned on.
Cheers,
Zoran Milojevic
