// Not all components may exist. If there are only 3 components, for example,
// the last one will have a length of -1 or 0 to indicate it does not exist.
// Note that many platforms' inet_addr will ignore everything after a space
// in certain circumstances if the stuff before the space looks like an IP
// address. IE6 is included in this. We do NOT handle this case. In many cases,
// the browser's canonicalization will get run before this which converts
// spaces to %20 (in the case of IE7) or rejects them (in the case of Mozilla),
// so this code path never gets hit. Our host canonicalization will notice
// these spaces and escape them, which will make IP address finding fail. This
// seems like better behavior than stripping after a space.
