I don't think @sds would mind if you made a pull request to include this in the documentation :-D

These options are all documented under https://github.com/causes/scss-lint/blob/master/lib/scss_lint/linter/README.md

Also, as of scss-lint 0.26.0 the name of the linter is included in the error output.
