Description
- If I use "ANALYZE TABLE t1,t2" with two tables, the PERSISTENT FOR clause in the second table t2 also affects the output for the first table t1

Another problem is that the documentation at https://mariadb.com/kb/en/analyze-table/ is obviously incorrect:
ANALYZE [NO_WRITE_TO_BINLOG | LOCAL] TABLE tbl_name [,tbl_name ...] |
[PERSISTENT FOR |
{ ALL |
| COLUMNS ([col_name [,col_name ...]]) INDEXES ([index_name [,index_name ...]])
|
}
|
]
|
It says the PERSISTENT clause is only possible after the table list. However in fact it's accepted after any tbl_name in the list.
