Summary: #ancestors never includes the singleton class (inconsistent)

Initial Comment:
Documentation of Module#ancestors states that the returned array includes the module itself, and it does so for both instances of both Module and Class. However, in singleton classes, the singleton class is not included in the array:

  module M; end
  class C; include M end
  c = C.new
  c_singleton = (class << c; self end)

  puts M.ancestors.inspect
  puts C.ancestors.inspect
  puts c_singleton.ancestors.inspect

yields
  [M]
  [C, M, Object, Kernel]
  [C, M, Object, Kernel]

in both
ruby 1.8.5 (2006-08-25) [i486-linux]
ruby 1.9.0 (2006-06-08) [i486-linux]
