Merge #4903

This change exports that modifier for doc comments so users can choose to highlight them differently compared to regular comments. Example: <img width="375" alt="Screen Shot 2020-06-16 at 10 34 14 AM" src="https://user-images.githubusercontent.com/1673130/84788271-f6599580-afbc-11ea-96e5-7a0215da620b.png"> CC @woody77 Co-authored-by: Paul Daniel Faria <[email protected]>
