Qt 5 to-do in QSettings

void QSettingsPrivate::iniEscapedStringList(const QStringList &strs, QByteArray &result, QTextCodec *codec)
{
    if (strs.isEmpty()) {
        /*
            We need to distinguish between empty lists and one-item
            lists that contain an empty string. Ideally, we'd have a
            @EmptyList() symbol but that would break compatibility
            with Qt 4.0. @Invalid() stands for QVariant(), and
            QVariant().toStringList() returns an empty QStringList,
            so we're in good shape.

            ### Qt 5: Use a nicer syntax, e.g. @List, for variant lists
        */

        for (int i = 0; i < strs.size(); ++i) {
            if (i != 0)
                result += ", ";
            iniEscapedString(strs.at(i), result, codec);
        }
    }
