-  # _nix completion is broken. Remove it; _nix provided by the nix
-  # package will be used instead. It is not sufficient to set low
-  # meta.priority below if nix is installed in the system profile and
-  # nix-zsh-completions in an user profile. In that case, the broken
-  # version takes precedence over the good one.
