      A double quote can start either a string or a line comment. Strings are
      ended before the end of a line by another double quote and can contain
      escaped double-quotes and post-escaped line breaks.

      Also, any double quote at the beginning of a line is a comment but we
      don't handle that properly at the moment: any double quote inside will
      turn them into a string. Handling it properly will require a smarter
