Space around operator of arithmetic expression

• No space around arithmetic operator

  Option: fmt094_space_around_operator = false, type: TFmtBoolean.

  SELECT *  
  FROM   dual  
  WHERE  1=-1  
         AND(1!=2  
              OR 2^=3)  
         AND 3<>4  
         AND 4>5; 

• Space around arithmetic operator
