Endless methods break ability to track namespacing

[zenspider]

Semi-related to #885 ... endless methods absolutely break class/namespace tracking:

class C
  def initialize = nil # :nodoc:
end

class D
  def initialize = nil # :nodoc:
end

class E
  def initialize = nil # :nodoc:
end

__END__

The following items are not documented:

In files:
* wtf.rb

  class C
  end


In files:
* wtf.rb

  class C::D
  end


In files:
* wtf.rb

  class C::D::E
  end
