Thanks for the clarifications.

advances begin(r) and decreases end(r) to produce a smaller range
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"
iterator_range make_super_range( range&, size_type left, size_type right = 0 );
decreases begin(r) and advances end(r) to produce a larger range
How about "extend_range"?
iterator_range make_range( range&, difference_type left, difference_type right = 0 );
does advance( begin(r), left ) and advance( end(r), right ) and is thus the most general.
I'm not sure I see why you need all three functions, particularly this last one.
