[Freeciv-Dev] (PR#10632) error in drawing of focus unit

The focus unit blinks every half-second or so.

However if, when the focus unit is not drawn, something causes that tile 
to be redrawn, the focus unit will always be drawn.  This happens most 
often with goto.  The biggest problem is that the tile is often only 
partially drawn.
