When you are /away
and someone sends you a private message, the system automatically replies with your away message.
How It Works
1. Set yourself away: /away Gone for lunch
2. When someone PMs you, they see: * YourNick is away: Gone for lunch
3. The auto-reply is sent only once per unique sender until you return.
Notes
Auto-replies are NOT sent for notices (per IRC convention). The replied-to set resets when you clear your away status.
