We don't use NEED_WORK_TREE when running the git-describe builtin, since you should be able to describe a commit even in a bare repository. However, the --dirty flag does need a working tree. Since we don't call setup_work_tree(), it uses whatever directory we happen to be in. That's unlikely to match our index, meaning we'd say "dirty" even when the real working tree is clean. We can fix that by calling setup_work_tree() once we know that the user has asked for --dirty. The --broken option also needs a working tree. But because its implementation calls git-diff-index we don‘t have to setup the working tree in the git-describe process.
