A test for irregular ID requirements and custom member action

This is a follow up for #351 Allow customized regexp for id in map.resources. The underlying issue seems to have been fixed somewhere in 2.3 but I don't see any unit tests for it, so the fix was probably a side-effect.

Including this unit test will stop any future regressions.

  def test_irregular_id_requirements_should_get_passed_to_member_actions 
    expected_options = {:controller => 'messages', :action => 'custom', :id => '1.1.1'} 
   
    with_restful_routing(:messages, :member => {:custom => :get}, :requirements => {:id => /[0-9]\.[0-9]\.[0-9]/}) do 
      assert_recognizes(expected_options, :path => 'messages/1.1.1/custom', :method => :get) 
    end 
  end
