+I (Luke Shumaker) wrote this patch to fix a bug where if Xinerama is
+(mis)configured such that there are two screens with the same size and
+position, then wmii removes both of them from the list, resulting in
+nscreens=0, which causes a segfault when it tries to dereference
+screen[0]. This is the case by default with a recent version of the
+drivers for my Nvidia 9400GT (where the DVI and VGA ports mirror
+eachother).
+
+Plus, the code's more efficient now, because it does everything in
+place, instead of needing to malloc another list.
