`self` always points current scope. so, to call class method from the
instance method, use `self.class.method_name`:

  module MyModule
    class MyClass
      def file_colon_line(*arg)
        self.class.textmate_colon_line(old_file_colon_line)
      end

      def self.textmate_colon_line(file_colon_line)
        # ...
      end
    end
  end
