Feature: Formatter API: Step file path and line number (Issue #179)
  To all reporter to understand location of current executing step let's fetch this information
  from step/step_invocation and pass to reporters

  Scenario: my own formatter
    Given a file named "features/f.feature" with:
      """
      Feature: I'll use my own
        because I'm worth it
        Scenario: just print step current line and feature file name
          Given step at line 4
          Given step at line 5
      """
    And a file named "features/step_definitions/steps.rb" with:
      """
      Given /^step at line (.*)$/ do |line|
      end
      """
    And a file named "features/support/jb/formatter.rb" with:
