If you are prefer to use spaces instead of tabs - in most cases you
don't want to see tabs anywhere (copy paste issues with other files).

This fixes several workflows:

- Creating new Debug file
- Creating new Tasks file
- Showing global settings (this one is cached, so it shows for the first
  time only right indentation, if you will change it will show old
  indentation till restart)
