An there is a difference between an empty range and a singular range.

Sorry to lower the tone, but can someone please explain exactly what a singular range is?

Presumably a range where at least one of the ends is a singular iterator, so roughly a range object that doesn't have an associated sequence of values. See 24.1/5 for a precise definition. (Draft available here, if needed: http://www.csci.csusb.edu/dick/c++std/cd2/lib-iterators.html)
