Actually ... wait a moment.  That does have some attraction independent
of performance questions, because what Alvaro suggested requires knowing
which commands support command triggers in two places.  Perhaps with
some refactoring we could end up with no net addition of cruft.

Personally, I'd really like to see the InvokeDDLCommandEventTriggers
macros go away; that's not a coding style I find nice.  If we had a
separate switch containing just the event-supporting calls, we could
drop that in favor of one invocation of the trigger stuff before and
after the switch.
