Function treatstackoption

** In function 'db_getinfo', the call to 'lua_getinfo' may push ** results on the stack; later it creates the result table to put ** these objects. Function 'treatstackoption' puts the result from ** 'lua_getinfo' on top of the result table so that it can call ** 'lua_setfield'. */
