33391	Clarify Aggregate.empty_result_set_value docs.	Claude Paroz	Mariusz Felisiak	"While translating the new docs, I struggled to understand the meaning of this sentence about `Aggregate.empty_result_set_value`:

  Override empty_result_set_value to None since most aggregate functions result in NULL when applied to an empty result set.

It's totally possible my limited English prevents me understanding this, in that case, maybe someone may explains that to me?
