ERC lacks support for user modes other than +o/+v (OP/VOICE), making it
difficult for IRC users to know what modes any user may have. Currently
user nicknames do not include any mode prefix by default. By setting
`erc-format-nick-function' to erc-format-@nick, a user can enable prefixes
@, or +, added to user nicknames. While that may be a sane default, most IRC
servers support more user modes. ERC already parses the prefixes sent in
the server parameters, and adds available modes to a list, but they are
never utilized.
