*istream& istream::operator>>(short& n) - extract short
*
*Purpose:
*       Extract short value from stream
*
*Entry:
*       n = value to update
*
*Exit:
*       n updated, or ios::failbit & n=SHRT_MAX/SHRT_MIN on overflow/underflow
*
*Exceptions:
*       Stream error on entry or value out of range
