True, although in that case the rail will just be drawn over the road.

Ugh, yes.  This would require a restructuring of that part of the
tilespec code.  I'm not quite ready for that, so instead here's a patch
that simply doesn't draw road corners at all (it draws rail corners, in
iso and non-iso view).
