* lib/delegate.rb (Delegator#respond_to_missing): warn if optional

  include_private argument is not false.  Delegator does (and
  should) not forward private methods.  [ruby-core:26080]

* lib/delegate.rb (Delegator#respond_to_missing): instead of
  redefining #respond_to?, use #respond_to_missing?.
