Ri Module#included entry is incorrect

This is the entry that is listed (below) if ri Module#included. In addition, it
would appear that there is no equivalent entry for the entry that is described. I am
running the following versions:
ri -v
ri: beta1 (1.2.2.8 2004/04/02)
ruby -v
ruby 1.8.1 (2004-04-27) [i686-linux]

I believe the correct description should be that included gets called whenever a
module is included in a class.

-------------------------------------------------------- Module#included
singleton_method_undefined(symbol)

ยทยทยท
 Document-method: singleton-method-undefined

  Invoked as a callback whenever a singleton method is undefined in
  the receiver.

     module Chatty
       def Chatty.singleton_method_undefined(id)
         puts "Undefining #{id.id2name}"
       end
       def Chatty.one()   end
       class << self
          undef_method(:one)
       end
     end

  <em>produces:</em>

     Undefining one
