status: support commands.status.relative config When the config is set to true, status output becomes relative to the working directory. This has bugged me since I started using hg and it turns it is sillily simple to support it (unless I missed something, of course). We could also add a --relative flag, but I would personally always want that on, and I haven't heard any use for having it sometimes on, so this patch only lets you enable it via config.
