[Carbon/Mac OS X] fringe-mode does not update frames

[nand]

On Carbon Emacs on Mac OS X,
(fringe-mode 'none) has no effect for frames which are already
displayed.

To repeat:

 * invoke Emacs.app
 * M-x fringe-mode <RET> none <RET>
 * (no change seen)

With the following patch, it seems to work fine for me.
But I doubt it is correct fix. (I wonder why are these
"x_set_fringe_width" commented out?)

Regards,
Nozomu Ando
