  * FIX #2722: update RULES for the Category/Arrow split
  
  The rule
  
  	arr id = id
  
  interacts unpleasantly with the advice to define
  
  	id = arr id
  
  in instances of Category that are also instances of Arrow (#2722).
  
  Also changed a couple of >>>'s to .'s in later rules.

    M ./Control/Arrow.hs -4 +2
