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