derived from #13973:

module A
  def foo
  end
end

module B
  def foo
  end
end

class C
  include A
  include B
end

c = C.new
m1 = c.method(:foo)
p m1.super_method         # => #<Method: A#foo>
p m1.clone.super_method   # => nil
p m1.unbind.super_method  # => nil

m2 = C.instance_method(:foo)
p m2.super_method         # => #<UnboundMethod: A#foo>
p m2.clone.super_method   # => nil
p m2.bind(c).super_method # => nil

super_method of binded/unbinded/cloned method should be super_method of original method, shouldn't it?
