Description:
When running SHOW CREATE USER on 8.0.3 and then running the result on 5.7.18 this happens:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'HISTORY DEFAULT PASSWORD REUSE INTERVAL DEFAULT' at line 1

I think SHOW CREATE USER on 8.0.3 should use: 
/*!800000 HISTORY DEFAULT PASSWORD REUSE INTERVAL DEFAULT */

Instead of:
HISTORY DEFAULT PASSWORD REUSE INTERVAL DEFAULT

How to repeat:
