<p>I think the cop doesn't quite do what I expect, or what it's documentation suggests - looking at <a href="https://github.com/rubocop-hq/rubocop/blob/master/lib/rubocop/cop/layout/heredoc_indentation.rb#L75">https://github.com/rubocop-hq/rubocop/blob/master/lib/rubocop/cop/layout/heredoc_indentation.rb#L75</a> it will bail out on a non-squiggly here doc if it has any identation. So it will only complain about unindented here docs and suggest indenting them with a squiggly here doc.</p>
