New warning "Useless localization of %s", based on
Subject: [PATCH] new warning "Useless localization of %s is deprecated"
Message-ID: <20030430201738.GA22054@fdgroup.com>
The proposed patch added this warning in the 'deprecated' category ;
I think this category is for things that exist and will be removed,
rather than for things that don't exist and that will maybe be added.
