The 'vis' treeview was updating twice per cursor motion.  Fixed.
(this makes the diff panel less slow)
The root cause might be a bug in pygtk.  The TreeView widget was 
emitting 'cursor-changed' twice instead of once, so this patch works 
around the issue by using only the first event per cursor position.
