Description:
I can make partitions and subpartitions with trailing
spaces in their names. This in itself might not be an
error (users and procedure variables can also have
trailing spaces in their names). But SHOW CREATE
TABLE doesn't use delimited identifers for partition
or subpartition names, so there is no way to know if
the spaces are there.

How to repeat:
mysql> create table t2 (s1 int) partition by list (s1) subpartition by hash(s1) 
                                          (partition p1 values in (1)
(subpartition s0), partition p2 values in (2) (subpa                            
              rtition `s0 `));
Query OK, 0 rows affected (0.01 sec)

mysql> show create table t2;
