+# Queries of the form:
+#
+#     SELECT group_concat(x) FROM (SELECT * FROM table ORDER BY 1);
+#
+# The ORDER BY would be dropped by the query flattener.  This used
+# to not matter because aggregate functions sum(), min(), max(), avg(),
+# and so forth give the same result regardless of the order of inputs.
+# But with the addition of the group_concat() function, suddenly the
+# order does matter.
