Description:
There is the problem checking permissions in HANDLER function,
if table is opened as some alias.

Test2 is used here as we have by default every user allowed to do everything he wants with "test" database.

How to repeat:
create database test2;
use test2;

mysql> CREATE TABLE foo (code SMALLINT NOT NULL PRIMARY KEY);
Query OK, 0 rows affected (0.01 sec)

mysql> INSERT INTO foo VALUES (1),(2),(10);
Query OK, 3 rows affected (0.01 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> GRANT SELECT ON test2.foo TO trouble@localhost IDENTIFIED BY 'trouble';
Query OK, 0 rows affected (0.01 sec)
mysql> quit

shell> mysql test2 -A -u trouble -ptrouble
mysql> HANDLER foo OPEN as foo1;
Query OK, 0 rows affected (0.00 sec)

mysql> HANDLER foo1 READ FIRST;
ERROR 1142: select command denied to user: 'trouble@localhost' for table 'foo1'
