Yes, that would work.  But the iterator would have to be passed by
value (as Glib::ustring::const_iterator) rather than by reference (as
const Glib::ustring_Iterator<T>&), which may be why you did it the
second way.

Does passing by value have any efficiency implications?  If so, it would
be better to provide a templated version of the comparison operators
which is separately typed on both arguments.
