EducateDashesOldSchoolInverted.

Parameters

string $_: Input text.

Return value

string 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.)
