-# Ticket #2942.  
-#
-# 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.
