Hack made to the wp-syntax plugin

I just made a couple of changes to wp-syntax as I noticed that when I fixed the ‘separating opening PHP tag’ issue the plugin was doing some weird stuff.

This is what I changed:

function wp_syntax_code_trim($code)
{
    // special ltrim b/c leading whitespace matters on 1st line of content
    $code = preg_replace("/^\s*\n/siU", "", $code);
    $code = rtrim($code);

	// This hack was added to prevent the adding of opening and closing tags just because
	if (strpos($code, '<?php') === false) {
		$code = '<?php' . "\n" . $code;
	}

	if (strpos($code, '?>', strlen($code)-2) === false) {
		$code .= "\n" . '?>';
	}
	// End hack
    return $code;
}

function wp_syntax_highlight($match)
{
    global $wp_syntax_matches;

    $i = intval($match[1]);
    $match = $wp_syntax_matches[$i];

    $language = strtolower(trim($match[1]));
    $line = trim($match[2]);
    $code = wp_syntax_code_trim($match[3]);

    $geshi = new GeSHi($code, $language);
    //$geshi->enable_keyword_links(false);

    $output = "\n<div class=\"wp_syntax\">";

    if ($line)
    {
        $output .= "<table><tr><td class=\"line_numbers\">";
        $output .= wp_syntax_line_numbers($code, $line);
        $output .= "</td><td class=\"code\">";
        $output .= $geshi->parse_code();
        $output .= "</td></tr></table>";
    }
    else
    {
        $output .= '<div class="code">';
        $output .= $geshi->parse_code();
        $output .= '</div>';
    }
    //return

    $output .= "</div>\n";

    return $output;
}
