The latter.

Right. I came up against the issue of whether begin() should return a
counting_iterator to the start of the range or simply the start of the range
itself, and stopped because I didn't know how to decide. I now think the
counting_iterator was a mistake. It's easy enough to write

    make_counting_iterator(r.begin())
