-/* Then there are seven single-bit flags that have the following meanings:
-  1. This character is the first of a two-character comment-start sequence.
-  2. This character is the second of a two-character comment-start sequence.
-  3. This character is the first of a two-character comment-end sequence.
-  4. This character is the second of a two-character comment-end sequence.
-  5. This character is a prefix, for backward-prefix-chars.
-  6. see below
-  7. This character is part of a nestable comment sequence.
-  Note that any two-character sequence whose first character has flag 1
-  and whose second character has flag 2 will be interpreted as a comment start.
 
-  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.
