Re: window configuration bug

Your patch fixes my problem, but introduces another one: 

(defun test ()
  (interactive)
  (let ((config (current-window-configuration)))
    (insert "hello")
    (set-window-configuration config)))

Hit 'C-x 2', then 'M-x test', and "hello" gets inserted, with the
point after the "o".  This is a fix of the bug I reported.

However, hit 'C-x 2 C-x o', so that I'm in the second window associated
to this buffer.  Move the point around and do 'M-x test': "hello" gets
inserted, but it gets inserted in the wrong place: not at the current
point, but instead at the point in the first buffer.  It appears that
the point is getting repositioned before the function is executed:
if I do 'M-x debug-on-entry test' in this situation, move the point
around and run 'M-x test', then as soon as the backtrace buffer
appears, the point has been moved.  In fact, if I do lots of things,
the point in the second buffer gets changed to the point in the first
buffer.  For example, if I type 'M-x debug-on-entry', then by the time
the prompt "Debug on entry (to function):" appears, the point has been
moved.
