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 .
```
In some cases, it may be useful to completely override the set ports for a given application - such as on initial deploy when there is no global domain set. This change also further allows us to handle automation in a smoother fashion.
