Any reason to prefer that approach?  It looks like the current one
(eof_iterator) meets all of my objectives.  I'm happy that the interface
looks like istream_iterator, which is familiar (end marker signalled via
default constructor).  It also calls the underlying function exactly the
correct number of times, another point in it's favor.
