This change

2015-09-30  Stefan Monnier  <[email-masked]>

	Try to avoid redisplaying all frames when creating a new one

	...

	* src/window.c (apply_window_adjustment): Remove redundant setting of
	windows_or_buffers_changed.

         ...

broke evaluating the following form with emacs -Q:

(set-window-scroll-bars nil 0 nil)

This should immediately remove the scroll bar of the selected window
but instead hides its right fringe under the scroll bar.
