format for correct pretty level

[Shmurdik]

foreach($arr as $k => $v) {
    if(is_string($v)) {
        $buf .= sprintf("%s\"%s\" \"%s\"\n", $line_indent, $k, $v);
    }
    else {
        $res = vdf_encode_step($v, $pretty, $level + 1);
        if($res === NULL) return NULL;

        $buf .= sprintf("%1\$s\"%2\$s\"\n%1\$s{\n%3\$s%1\$s}\n", $line_indent, $k, $res);
    }
}
