will '$SYS/brokers/' publish match '#' or '+/#'?

0.8.2 seems still can not use + on $SYS
I test :
$SYS/borkers/+/clients/+/connected
$SYS/borkers/emqttd@127.0.0.1/clients/+/connected
both can't receive client connect info

[emqplus]

Two issues:

1. The topic should be '$SYS/brokers/+/clients/+/connected', ‘borkers' in wiki is a spelling error.
2. mosquito_pub/sub will generate a random clientId that contains '/', for example:

mosqpub/88741-iMac.loca

Then "clients/+/connected" cannot match the presence topics, have to use '$SYS/brokers/+/clients/#'

[emqplus]

Example:

iMac:~ feng$ mosquitto_sub -t '$SYS/brokers/+/clients/#' -d
Client mosqsub/88740-iMac.loca sending CONNECT
Client mosqsub/88740-iMac.loca received CONNACK
Client mosqsub/88740-iMac.loca sending SUBSCRIBE (Mid: 1, Topic: $SYS/brokers/+/clients/#, QoS: 0)
Client mosqsub/88740-iMac.loca received SUBACK
Subscribed (mid: 1): 0
Client mosqsub/88740-iMac.loca received PUBLISH (d0, q0, r0, m0, '$SYS/brokers/emqttd@127.0.0.1/clients/mosqpub/88741-iMac.loca/connected', ... (105 bytes))
{"username":"undefined","ipaddress":"127.0.0.1","session":false,"protocol":3,"connack":0,"ts":1433243924}
Client mosqsub/88740-iMac.loca received PUBLISH (d0, q0, r0, m0, '$SYS/brokers/emqttd@127.0.0.1/clients/mosqpub/88741-iMac.loca/disconnected', ... (35 bytes))

The messages published to $SYS/# will not match topic filters: #, +/#...
