It looks like they were originally used to detect cyclic dependencies, as
in the example in the documentation:

  http://www.boost.org/libs/graph/doc/file_dependency_example.html

But they aren't actually used at all, because they aren't needed. I'm
removing them and resynchronizing the documentation with the example code.

Thanks for finding this!
