When [`username_format`](https://halloy.chat/configuration/buffer#username-format) is set to `full`, it would be nice to display the user's realname as well (as WeeChat does). For reference, the [WeeChat join message](https://github.com/weechat/weechat/blob/f48b0bae2e7db5ec806bb50684f5b7fe2893604f/src/plugins/irc/irc-protocol.c#L1844-L1859) looks like this: ``` nickname [accountname] (realname) (username@host) has joined #channel ```
