At the moment, it's not possible to pass the object returned by boost::ref as
visitor to the breadth_first_search function. So, if visitor has state, I
need to hold that state by pointer, which is inconvenient.

Any opinions on the attached patch? Unless there are any objections, I'll
commit it after we branch for release.
