Ready for review.

- Split BreakableComment back into a BreakableBlockComment and BreakableLineCommentSection
- Extract common reflow computation functionality
- Put LastLineNeedsDecoration and Decoration and Prefix to the appropriate subclasses
- Fixed a double indentation bug caused by the WhitespaceManager.
- Implement a simple heuristic to detect ascii-art to stop reflow early
