One thing you missed is that the detailed menu in emacs.texi also
needs to be updated, exactly like you did here:

>  @menu
>  * Package Menu::         Buffer for viewing and managing packages.
> +* Package Statuses::     Which statuses a package can have.
>  * Package Installation:: Options for package installation.
>  * Package Files::        Where packages are installed.
>  @end menu

Thanks.
