Another Window Display Bug

[Nick Roberts]

This bug relates to this change:

2003-05-24  Kim F. Storm  <address@hidden>

        1) Swap the position of fringes and display margins in windows, i.e.
        the fringes are now displayed between the margins and the text area
        (by default).

It occurs when a window with a display margin is replaced by one without.
It can be reproduced as follows (please forgive the same old context):

A C program myprog compiled with -g using two files, main.c and myproc.c, say.

Type M-x gdba,

Run myprog under gdb:
(Run gdba (like this): gdb -annotate=2 -noasync myprog)
The GUD buffer and the file main.c should appear in two windows

Type break main in the GUD buffer and the display margin with a breakpoint 
should appear in the window holding main.c.

Step through the program. When it enters myproc, myproc.c is displayed without
the display margin. However, the fringe is jumbled with the remains of the
margin (before the overlay-arrow?).
