cmd_current which calls cmd_list doesn't print newline after showing desks.

```
~ λ desk
No desk activated.

dart
rest ~ λ desk list
dart
rest
~ λ desk
No desk activated.

dart
rest ~ λ
```

```
~ λ desk --version
◲ desk 0.6.0
```

Probably doesn't need to be noted but my prompt is `~ λ `.

Looked at `desk`, but didn't understand why it does this if it's just calling `cmd_list`.

Reproduce the output shown for `desk` and `desk list`, then inspect the `cmd_current` and `cmd_list` entry points mentioned in the issue. Determine why the current command omits a trailing newline when it calls the list command; done means the displayed desks are followed by a newline without changing the listed content.
