       Now 83 characters fit on the screen.  But we still get:

   Can you debug it and fix it?

The problem is that the bug does not seem to be in `fringe-mode', but
in parts of the C code that are supposed to resize X windows.  I am
not very familiar with that stuff.

The problem is that if I use `modify-frame-parameters' to change the
`left-fringe' or `right-fringe' parameters, then (frame-width)
actually _should_ stay the same, but the X window should narrow or
broaden.  This does not happen.

Note, by contrast, that if I use `modify-frame-parameters' to change
`menu-bar-lines', then the X window _does_ grow smaller or taller.
