Improvement suggestion: 60-galera.cnf comes without wsrep_provider

When a Galera Cluster is installed a Galera config (60-galera.cnf) is provided:

[galera]

1. Mandatory settings
   #wsrep_on = ON
   #wsrep_cluster_name = "MariaDB Galera Cluster"
   #wsrep_cluster_address = gcomm://
   #binlog_format = row
   #default_storage_engine = InnoDB
   #innodb_autoinc_lock_mode = 2

1. Allow server to accept connections on all interfaces.
   #bind-address = 0.0.0.0

1. Optional settings
   #wsrep_slave_threads = 1
   #innodb_flush_log_at_trx_commit = 0

In this config some outcommented variables are set. But wsrep_provider is missing!!! Without this variable the node will not start with the Galera plug-in enabled. It took me a few minutes to find out, what was missing. I guess that some newbies will take much longer and give up frustrated?

Suggestion: Add # wsrep_provider = /usr/lib/libgalera_smm.so to the config so we do not forget the parameter.
