  * Fix Trac #2861: bogus eta expansion
  
  Urghlhl!  I "tided up" the treatment of the "state hack" in CoreUtils, but
  missed an unexpected interaction with the way that a bottoming function
  simply swallows excess arguments.  There's a long
       Note [State hack and bottoming functions]
  to explain (which accounts for most of the new lines of code).
  

    M ./compiler/coreSyn/CoreUtils.lhs -16 +53
