If the common type of begin and end is unsigned and end is 0 the private member pastEnd ends up being unsigned.max due to "pastEnd - 1" (used to make end not inclusive) which results in iota behaving incorrectly. A simple change to always make an empty range when begin==end prevents this. Also fixed and clarified the documentation.
