    Fix integer overflow caused by bad use of binary operator.
    
    Guess this may make the AI more accurate :)
    
    Problem caught by gcc:
    
    ../../gnushogi/search.c: In function 'search':
    ../../gnushogi/search.c:887: warning: overflow in implicit constant conversion
    
    
    A quick audit only revealed a place where another logical AND was
    tested using a curious idiom, so let's make it consistent at the same
    time.
