Represents a bidirectionally-iterable view of non-overlapping code point subranges. Each subrange represents the code points between one allowed line break and the next. Each subrange is lazily produced; an output subrange is not produced until an iterator is dereferenced. Each element has a member function bool hard_break() that indicates whether the end of the subrange is at a hard line break, or just an allowed line break location.
