44 **  Check for Condition After a Move
45 **
46 **	Various ship conditions are checked.  First we check
47 **	to see if we have already lost the game, due to running
48 **	out of life support reserves, running out of energy,
49 **	or running out of crew members.  The check for running
50 **	out of time is in events().
51 **
52 **	If we are in automatic override mode (Etc.nkling < 0), we
53 **	don't want to do anything else, lest we call autover
54 **	recursively.
55 **
56 **	In the normal case, if there is a supernova, we call
57 **	autover() to help us escape.  If after calling autover()
58 **	we are still in the grips of a supernova, we get burnt
59 **	up.
60 **
61 **	If there are no Klingons in this quadrant, we nullify any
62 **	distress calls which might exist.
63 **
64 **	We then set the condition code, based on the energy level
65 **	and battle conditions.
