38 ** Automatic Override
39 **
40 ** If we should be so unlucky as to be caught in a quadrant
41 ** with a supernova in it, this routine is called. It is
42 ** called from checkcond().
43 **
44 ** It sets you to a random warp (guaranteed to be over 6.0)
45 ** and starts sending you off "somewhere" (whereever that is).
46 **
47 ** Please note that it is VERY important that you reset your
48 ** warp speed after the automatic override is called. The new
49 ** warp factor does not stay in effect for just this routine.
50 **
51 ** This routine will never try to send you more than sqrt(2)
52 ** quadrants, since that is all that is needed.
