This fixes several bugs with regards to line breaks and comments:

 - any unicode line break (line feed, vertical tab, form feed, carriage
   return, NEL, LS and PS) is considered to terminate a single-line
   comment. The line break itself is considered to be the next token
   after the comment, leading to a parser error if it is not an
   ascii character (i.e. for NEL, LS and PS).
 - unterminated multiline comments are considered illegal tokens
 - '/** /' is considered an unterminated multiline comment
   (previously, whitespace was allowed before the last '/'
