The currently used idiom for handling key specific subcompletions
did not work here: behind `docker event -f type=network `, the completion
of networks triggered. The expected behaviour is not to complete
anything here.
In order to limit the scope of the corresponding PR, the new idiom is
currently only used in `docker events --filter`.
