function EducateDashesOldSchoolInverted($_) {

  #

  #   Parameter:  String.

  #

  #   Returns:    The string, with each instance of "--" translated to

  #               an em-dash HTML entity, and each "---" translated to

  #               an en-dash HTML entity. Two reasons why: First, unlike the

  #               en- and em-dash syntax supported by

  #               EducateDashesOldSchool(), it's compatible with existing

  #               entries written before SmartyPants 1.1, back when "--" was

  #               only used for em-dashes.  Second, em-dashes are more

  #               common than en-dashes, and so it sort of makes sense that

  #               the shortcut should be shorter to type. (Thanks to Aaron

  #               Swartz for the idea.)

  #                      en         em
