Description:
When executing a query which doesn't use an index (or use a bad index), mysql->server_status doesn't contain flags SERVER_QUERY_NO_INDEX_USED/SERVER_QUERY_BAD_INDEX_USED

How to repeat:
...
mysql_query(mysql, "DROP TABLE IF EXISTS foo");
mysql_query(mysql, "CREATE TABLE foo (a int)");
mysql_query(mysql, "INSERT INTO foo VALUES (1),(2),(3),(4),(5),(6)");
mysql_query(mysql, "UPDATE foo SET a =1 WHERE a=5");
if (mysql->server_status & SERVER_QUERY_NO_INDEX_USED)
	printf("No index used!\n");
...
