Editorconfig can only act based on file extension and path, not attributes, it remains a mean only for multiple collaborators to use the same configuration on their editor. When it is too restrictive, such as not considering the file syntax, use a lint tool for the specific file type instead of trusting editorconfig. Changes were made to increase readability.
