- bit 6 is used to discriminate between two different comment styles.
- Languages such as C++ allow two orthogonal syntax start/end pairs
- and bit 6 is used to determine whether a comment-end or Scommentend
- ends style a or b. Comment start sequences can start style a or b.
- Style a is always the default.
