[pbs-devel] [PATCH proxmox] router: format: add newline at the end

[Maximiliano Sandoval]

Without this newline running commands with missing arguments, e.g.
```
proxmox-backup-client backup
```

will print their usage string without a newline at the end, which is
costing me my sanity.

As per [1], usage shouldn't contain trailing new lines and this in
principle should not print double new lines.
