+**  CAUSE SUPERNOVA TO OCCUR
+**
+**	A supernova occurs.  If 'ix' < 0, a random quadrant is chosen;
+**	otherwise, the current quadrant is taken, and (ix, iy) give
+**	the sector quadrants of the star which is blowing up.
+**
+**	If the supernova turns out to be in the quadrant you are in,
+**	you go into "emergency override mode", which tries to get you
+**	out of the quadrant as fast as possible.  However, if you
+**	don't have enough fuel, or if you by chance run into something,
+**	or some such thing, you blow up anyway.  Oh yeh, if you are
+**	within two sectors of the star, there is nothing that can
+**	be done for you.
+**
+**	When a star has gone supernova, the quadrant becomes uninhab-
+**	itable for the rest of eternity, i.e., the game.  If you ever
+**	try stopping in such a quadrant, you will go into emergency
+**	override mode.
