Comment(by jmr@…):

 First the port-rdeps script in contrib/ should be integrated into base as
 e.g. 'port rdeps'. I would then propose adding the following selectors:
  * deps:  direct dependencies of the given port
  * rdeps: recursive dependencies
  * dependents: ports that directly depend on the given one according to
 the registry
  * rdependents: recursive version of dependents

 We should not change the behaviour of the current depends: selector as it
 is useful in its own right.
