  * Permit arity-raising of cafs/functions in hat-observe.  Unfortunately,
  the equations you see can be confusing, so this feature should be
  considered experimental.  For instance, if
      f x = g x
      g x y = x+y
  then observing `f' shows e.g. `f 1 = g 1', but observing `f _ _' shows
  e.g. `g 1 2 = 3', not `f 1 2 = 3' as you might expect.
  
  This commit also fixes the `:set recursive off' bug whereby observing
  `f in f' showed the non-recursive calls of f instead of the recursive
  ones.
