I think you have little choice but to add the parameter because the current
implementation of emptyNavigableSet().descendingSet().comparator() returns the
wrong value. Which should mean that the bounds checking is incorrect in the
descendingSet too. Am I correct on that? So by adding that feature you don't
have to create a special subclass to correctly implement EmptyNavigableSet.
