Especially after i see https://ftp.gnu.org/old-gnu/Manuals/coreutils-4.5.4/html_node/coreutils_58.html

i see includes an example

```rust
 	

newline='
'
ls -l --time-style="+%Y-%m-%d $newline%m-%d %H:%M"
ls -l --time-style="iso"
``

one of these examples is, i runned the second

```rust

```

and i see uutils breaks the official gnu example and not work properly, that must be fixed
