Anything that moves point of that buffer elsewhere.  This includes
selecting another window on that buffer whose window-point does not
equal that of the window we switched away from.

Right.  Maybe we should call 'switch-to-buffer' here so people with
'switch-to-buffer-obey-display-actions' non-nil get the
'pop-to-buffer-same-window' behavior and others are unaffected.  Let's
wait for Juri to comment.
