Comment 9 for bug 485017

To quote the illustrious Youness Alaoui from the empathy bug:

> The problem is that it's not the nickname that's being used in aMSN, it's the
> 'Friendly name'.. MSN has the ability to specify a "friendly name" *per
> message*.. this allows people to have huge ascii-art nicknames that do not
> bloat the chat windows when chatting. That's also what groups.im uses, I can
> confirm.
> This "Friendly name" is sent as a header in the message, the header is called
> "P4-Context". papyon supports it and sets it as the message.display_name on the
> event on_conversation_message_received.
> Telepathy-butterfly does not support it though.
