 * Known issues:
 *
 * - invalid hex string literals will be recognized as a double quoted strings
 *   but 'x' at the beginning of string will not be matched
 *
 * - delimited string literals are not checked for matching end delimiter
 *   (not possible to do with js regexp)
 *
 * - content of token string is colored as a string (i.e. no keyword coloring inside a token string)
 *   also, content of token string is not validated to contain only valid D tokens
 *
 * - special token sequence rule is not strictly following D grammar (anything following #line
 *   up to the end of line is matched as special token sequence)
