With this patch, the mode-lines are redrawn when they are exposed.
But I also observe that a mode-line part is not updated with the last
C-x o (see the 3rd mode-line in the screenshot) with the previously
mentioned procedure on the Mac port.  Strangely, if I try C-x o three
times further, then the second mode-line part is also not updated.
Unfortunately, I couldn't reproduce it with Cent OS 5.11.
