+/* 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. The char is part of a delimiter for comments of style "b".
+ 7. This character is part of a nestable comment sequence.
+ 8. The char is part of a delimiter for comments of style "c".
+ 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 and 8 are used to discriminate between 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 markers can start style a, b, c, or bc.
+ Style a is always the default.
+ For 2-char comment markers, the style b flag is only looked up on the second
+ char of the comment marker and on the first char of the comment ender.
+ For style c (like to for the nested flag), the flag can be placed on any
+ one of the chars.
