> so that repl status returns that and next incremental can specify it as the

> notification event missing error if the older events are cleaned by the
> cleaner.

> events were cleared, the min and max id at that time
> ** how many events were cleared
> ** min and max id after the cleaning.
> * In REPL::START document the starting event, end event if specified and the
> maximum number of events, if specified.
