As long as it is clearly documented that "none" is given explicitly
when no filtering is requested (Jeff's point of making it possible
to tell the reason why we are not requesting is still valid), I
think it would be OK.  If we are giving enough log entries for
"fetch" operation, another "empty" message would not hurt (if the
trace for "fetch" is otherwise very quiet, then an unused "empty"
may become distracting, but I somehow do not think it is the case).

Thanks.
