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.

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

They are (or can be), see above.
