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.
