rcirc: Skipping /away messages using handlers

 
 4.1 Skipping ‘/away’ messages using handlers
 ============================================
 
 The IRC protocol specifies how certain events are signaled from server
 to client.  These events have numbers and are dealt with using so-called
 handlers.  You can override existing handlers by exploiting the naming
 convention adopted for ‘rcirc’.
 
    Here’s how to stop ‘rcirc’ from printing ‘/away’ messages.  Since
 ‘rcirc’ doesn’t define a 301 handler, you don’t need to require ‘rcirc’
 before defining the handler:
 
      (defun rcirc-handler-301 (process cmd sender args)
        "/away message handler.")
