     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.
