 // or if there are any non-7-bit characters or other characters that can not
 // be in an IP address. (This is important so we fail as early as possible for
 // common non-IP hostnames.)
 //
 // 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 platform's inet_addr will ignore everything after a space
 // in certain curcumstances 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.
