Comment(by charris):

 Subtracting unsigned numbers from each other is a well defined operation,
 so this is a case of user beware. However, it is probably not what is
 expected. I think adding a note to the doc string and maybe an example
 would clarify things. Or we could raise a warning. In the latter case
 there should first be some discussion on the mailing list.
