What does this change?
* Remove use of spaces for formatting
These could be found by using `grep -r -l -P '^\t+ +[^*]'
* Removal of training whitespaces
* A few lines longer than 120 chars
This better reflects its purpose as otherwise it would imply
that you need Elastic Stack for it. Graylog also reads from
Elasticsearch instances, this could serve as additional integration
here.
