Re: Function: window-fringes

[Richard Stallman]

    You can set it with set-window-fringes, directly through the variables
    left-fringe-width or right-fringe-width and probably with
    modify-frame-parameters (or specifying frame parameters).

Judging from reading the code, I don't think that the values of
left-fringe-width and right-fringe-width have any effect on the value
of WINDOW_LEFT_FRINGE_WIDTH, on a tty frame.  I don't think that
trying to specify the frame parameter has any effect on the frame
fringe width, on a tty frame.  Have you actually observed that either
of these actions has such an effect?

It looks like set-window-fringes really can set the frame width
slots.  I think that is the bug.  So let's change it not to set them
on a tty.

With the following change, does any of this problem persist?
