Trying to use a blank host value for table-specific or collumn-specific privileges does not work as expected. Using a blank value results in non-working privilege. Using a '%' for the host value does work as expected. These should be equivalant values, according to secion 5.4.6 of the documentation.

How to repeat:
Create a user with only 'usage' privilege on a database. Then assign a table or collumn-specific privilege to the user, with a blank host value in tables_priv or collumns_priv. The user will not have the expected privilege.

Change the blank value to a '%' and the privilege will work as expected.

Please note that the user in question has a blank host value in the 'user' table as well (ie for the 'consult the host table' behavior).

FYI This happens on v 3.23.58 as well

Verified with 4.0.18 and 4.1.2:

GRANT ALL ON test.t1 TO testuser@'';
SHOW GRANTS FOR testuser@'';
SHOW GRANTS FOR testuser@'';
