fixed here-string formating

Resubmitting pull-request. Corrected line-ending issues.
Comments are only preserved if they are part of the data object (i.e. `comment: Comment here`), but not if they are language comments.

I generally prefer to only edit the YAML and put a few language comments next to my stuff. I also indent multi-line expressions in a certain way and I'm actually not sure if they are preserved.
