From the redbook:

	If there is a current point, the arc operator includes a straight
	line segment from the current point to the first endpoint of this
	arc and then adds the arc itself into the current path.  If the
	current path is empty, the arc operator does not produce the
	initial straight line segment.  In any event, the second endpoint
	of the arc becomes the new current point.
