Add prompt when Ctrl-C pressed (#702)

Browse Source 
When I play the pubsub command in console, I am confused by the
following scenario:

The reason is that when I press Ctrl-C, client exits current connection
and reconnects to the server.
Thus I add one prompt message to make everyone clear what it happens.
