Wraps the conditions in a having (…) clause, filtering grouped solutions by aggregate conditions the way
filter constrains ungrouped ones; several conditions are each bracketed and conjoined with &&, the form
portable across engines. Empty conditions, such as those produced by nil, are dropped first; an empty list
yields the empty fragment, leaving the grouped solutions unfiltered.
