/// into a string suitable for the Host field, adding square brackets to
/// the host when necessary.
/// 
/// Note that the Path field is stored in decoded form: /%47%6f%2f becomes /Go/.
/// A consequence is that it is impossible to tell which slashes in the Path were
/// slashes in the raw URL and which were %2f. This distinction is rarely important,
/// but when it is, the code should use the [URL.EscapedPath] method, which preserves
