          The format of the returned path depends on the value of ``which``:
  
          available_repositories
              /repository_sets/<id>/available_repositories
          enable
              /repository_sets/<id>/enable
          disable
              /repository_sets/<id>/disable
  
          ``super`` is called otherwise.
