Hm?  I wasn't suggesting removing the ExplainBeginOutput call, but more

+                       ExplainOpenGroup(...);
                        ExplainQueryText(&es, queryDesc);
                        ExplainPrintPlan(&es, queryDesc);
+                       ExplainCloseGroup(...);

Details still TBD; the point is just that it's not clear to me why
auto_explain should need a formatting concept that doesn't already exist
within explain.c.
