Number data limit?

[ksnyder]

Was curious about the limit on number data in formatter.rb:

  def send_number_data(num)
    if num < 0 || num >= 4294967296
      raise Net::IMAP::DataFormatError, num.to_s
    end
    put_string(num.to_s)
  end

We are sending Gmail msgids, which are larger than this limit, and they work fine through Net::IMAP.
