This is useful in cases where the command output must be tested, but it is otherwise embedded in a specific part of the dokku core.
As the 'plugin' commands require root, this is safe to add to the core.
While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
