I think that where the Portal gets a tag is in PortalDefineQuery,
and that's normally set as a result of parsing.  The code earlier in
PortalRunMulti is meant to supply run-time-determined tags, such
as INSERT/UPDATE/DELETE with a row count.  I guess if you hold
your head at the right angle, the case we're considering now is
a run-time-determined tag for the outer EXECUTE.
