[Message part 1 (text/plain, inline)]
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

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'.
