delivery.ManifestAccepted.EventID now names, for an event with no digest, the module and the event's revision (J3,
ruling A5(d)), so the indexer drops its own left id. The revision is the modules state's revision of the value that left
(write hands the revision it read), so two leaves of one module are two events; asked again by hand for a module no
longer held it is 0, and the again suffix keeps it unique. Row in TestAMergeThatRemovesAModuleDeletesItsKey (failed
first: Revision 0, id naming the last digest).
