manual.texi bug was described incorrectly

Fixed problem when using the @code{GRANT FILE ON database.* ...}; Previously

we added the @code{DROP} privilege for the database.

@item

Fixed that @code{DELETE FROM table_name ... LIMIT 0} and

@code{UPDATE FROM table_name ... LIMIT 0} doesn't delete/update anything.

Fixed @code{DELETE FROM table_name ... LIMIT 0} and

@code{UPDATE FROM table_name ... LIMIT 0} acted as though the @code{LIMIT}

clause was not present (they deleted or updated all selected rows).

@item

@code{CHECK TABLE} now checks if an auto_increment column contains the value 0.
