Can you change the commit message? "$config" is missing there.

Is this the correct use?

    var $geshiScript = 'geshi.php';

    function setGeshiPath($path) {
            $this->_setPath($this->geshiScript, $path, 'geshi.php');
    }

    function getGeshiScript() {
            return $this->geshiScript;
    }

Is this the correct use?

    var $geshiScript = 'geshi.php';

    function setGeshiPath($path) {
            $this->_setPath($this->geshiScript, $path, 'geshi.php');
    }

    function getGeshiScript() {
            return $this->geshiScript;
    }

Yes, this is my understanding. Please give it a try.

Ok. I have tested my current PR, and it works for me

Thank you. You are right. I fixed it.
