* bug#14200: 24.3; Window fringes / margins get reset on switching buffer

If in emacs -Q, I evaluate:

(set-window-margins nil 5 5)
(set-window-fringes nil 16 16)

and switch to a different buffer, the fringes/margins will be reset. They
will still be frame-default if I switch back to the same buffer.

Btw, I think it would make more sense, if the above settings where attached
to a buffer and not a window. At the same time there is a buffer-local
variable called window-size-fixed, which looks like it should be a window
property.

If you want the values you set be preserved for that buffer, you need
to set the buffer-local values of left/right-margin-width and
left/right-fringe-width.  If you want them to be preserved in a window
regardless of the buffer it displays, switch to another buffer by
invoking set-window-buffer with non-nil 3rd argument.

They are (or can be), see above.

Thanks, but changing those variables (or the corresponding fringe ones)
doesn't seem to have any effect. emacs-version: GNU Emacs 24.3.1
(x86_64-unknown-linux-gnu, GTK+ Version 2.24.13) of 2013-03-05 on ubuntu

From the ELisp manual:

     Setting these variables does not immediately affect the window.
  These variables are checked when a new buffer is displayed in the
  window.  Thus, you can make changes take effect by calling
  `set-window-buffer'.
