 If I have a /test/ endpoint, it will not show in query_vars unless it has
 a value. So /test/1 will have query_vars[test]=1 but /test/ will NOT have
 query_vars[test]=null in query_vars. Empty endpoints should be present
 with null value in query_vars so they can be tested with isset() for
 value-less existence.

 Hope it make sense. Tested in 3.0.1 and this problem exists.
