24.0.50; fringe-mode value of `half' is broken |

emacs -Q
M-x fringe-mode
Enter `half'.
The fringe values (both left and right) should each be 5, according to
the code and comments. Instead, it is still 8, as shown by
(frame-parameters). There is no difference in behavior between `half'
and `default'. Dunno whether this is Windows-specific.

I changed fringe.el to use (4 . 4). So this bug should be fixed now
(revno 101464).
