In any case, it's some irrelevant for non-random-access iterators as iterator_range::size() is only defined for random access iterators, no?

Sorry, I was a bit hasty in my previous reply. Yes, I'm surprised to say that iterator_range::size() is implemented for random access iterators only. Nevertheless, there's still no reason to make its return type signed.
