Feature: Issue #188: Better diagnostics if nested step is undefined
  
  . Currently if nested step has no match, it's shown like this:
  .
  .     Assertion Failed: Sub-step failed: When I do strange thign
  .     Substep info: None
  .
  . Took some time to find that typo.
  . The suggestion is to fill substep error_message with at least "No match for step"
  . so it would become:
  .
  .     Assertion Failed: Sub-step failed: When I do strange thign
  .     Substep info: No match for step
  .
  . IMPLEMENTATION NOTE:
  . A slightly different output is provided:
  .
  .     Assertion Failed: UNDEFINED SUB-STEP: When I do strange thign

    Given a new working directory
    And a file named "features/steps/steps.py" with:

      def step_good_diagnostic_message_is_shown(context):
          pass

      @step('I execute nested steps with an undefined step')
      def step_passes(context):
          context.execute_steps(u'''
            Given another step passes
            When an undefined, nested step is executed
            Then third step passes
          ''')
