Galera status documentation missing 'wsrep_local_state_comment' and others

Running "show status like '%wsrep%'" returns 58 records in my version of Mariadb/Galera (10.1.18). Only 33 are defined in the documentation here:
https://mariadb.com/kb/en/library/getting-started-with-mariadb-galera-cluster/#configuration-and-monitoring

Among the missing is 'wsrep_local_state_comment' which is certainly useful for understanding the cluster status.

It would be great to have all 58 documented, or more explicitly refer to codership documentation if it can be used.
