PHP: wrong style on extra highlighted lines

[Blaimi]

example:

<?php
require_once 'geshi.php';
$content = <<<CODE
01st line
02nd line
03rd line
04th line
05th line
06th line
07th line
08th line
09th line
10th line
11th line
12th line
CODE;

$geshi = new GeSHi($content, 'text');
$geshi->highlight_lines_extra(1, 'background-color:red');

$geshi->highlight_lines_extra(3, 'background-color:red');
$geshi->highlight_lines_extra(4, 'background-color:red');

$geshi->highlight_lines_extra(6, 'background-color:red');
$geshi->highlight_lines_extra(7, 'background-color:red');
$geshi->highlight_lines_extra(8, 'background-color:red');

$geshi->highlight_lines_extra(10, 'background-color:red');

echo $geshi->parse_code();

solution:
add '+1' in lines 4007 and 4055 (geshi.php 1.0.8.11)

ah, and BTW: The second parameter is not documented …
