* Remove modify_hr_tags method definition this breaks things that call it. * Remove direct uses of modify_hr_tags fixer method Remove from class METHODS lists, remove test cases about this behavior, and remove from methods lists in test cases. * Remove hr tag modification spec Still don't understand what problem this was fixing, but I've removed the test case.
