Since you have a template iterator_range and a corresponding object generator
amke_iterator_range, I would expect make_sub_range to be an object generator
returning a sub_range.

So I would prefer the name "restrict_range"

 How about "extend_range"?

I'm not sure I see why you need all three functions, particularly this last one.
