People can write master short for refs/heads/master, but can't with refs/heads/@. Would it be better to detect if dwim_ref("@") exists, then disable special '@' and warn user to rename '@' to something else? After they have renamed it, make '@' special and forbid it in any component in the ref (i.e. refs/heads/@ is forbidden too). -- Duy
