Description:
SHOW GRANTS isn't consistent about quoting
in its output.

How to repeat:
Let's say I issue these statements:

GRANT SELECT on world.* TO abc@localhost;
GRANT SELECT on world.City TO abc@localhost;
GRANT SELECT (ID) on world.City TO abc@localhost;

Then I issue SHOW GRANTS:

mysql> show grants for abc@localhost;
+------------------------------------------------------+
| Grants for abc@localhost                             |
+------------------------------------------------------+
| GRANT USAGE ON *.* TO 'abc'@'localhost'              |
| GRANT SELECT ON `world`.* TO 'abc'@'localhost'       |
| GRANT SELECT (ID) ON world.City TO 'abc'@'localhost' |
+------------------------------------------------------+

Note that world is quoted in the second GRANT
statement, but that world and City are not in the
third statement.

I guess this is just cosmetic in a sense, but if
the db or table names happened to contain
special character, the lack of quotes would be
incorrect.
