Pivotal's packaging of RabbitMQ shows a banner at the end of the plugin
listing talking about their official plugins. The start of the banner is
divided by a blank line so the changed plugin listing will now
break after the first empty line.
An example listing with the rabbitmq_management plugin enabled:
```
$ rabbitmq-plugins list -E -m
rabbitmq_management
Pivotal officially maintains and supports the plugins:
rabbitmq_auth_backend_ldap, rabbitmq_auth_mechanism_ssl,
rabbitmq_consistent_hash_exchange, rabbitmq_federation,
rabbitmq_federation_management, rabbitmq_jms_topic_exchange,
rabbitmq_management, rabbitmq_management_agent,
rabbitmq_mqtt, rabbitmq_shovel, rabbitmq_shovel_management,
and rabbitmq_stomp.
