Yep. Realistically, I usually don't use the <dtml-sqlgroup> and
<dtml-sqltest> for most things, but for complicated cases where might be
emitting one or more of several where clauses, there can be very helpful.

I would always use two myself; I suppose that some would argue that for
simple selects, the speed/memory is insignificant. I prefer two in all cases
beacuse it's clearer.
