Running ufed, shows that the vanilla flag has this description: "Keep the kernel sources in a vanilla state and do not apply anyting." Mutt has the vanilla flag, which means the description of this use flag no longer makes sense. I don't even like this flag being there at all. It seems stupid to have a flag which can apply three patches, or not.
no, use.local.desc just never had vanilla for net-mail/mutt described in it
fixed
