code: private void consumeCRLF(ImapRequestLineReader request)
              throws ProtocolException {
          char next = request.nextChar();
          if (next != '\n') {
              consumeChar(request, '\r');
          }

      }
docs: Consumes a CRLF from the request.
  TODO we're being liberal, the spec insists on \r\n for new lines.
