Google-hilite bug (and fix)

The google-hilite plugin has a bug where an empty search string from the wordpress internal search (i.e., http://myblog.com/?s=) results in the entire URL being sent as the search string. The unescaped slashes then raise a PHP error.
The fix: Change the preg_replace which is extracting the wordpress search from:
$query_terms = preg_replace(‘/^.*s=([^&]+)&?.*$/i’,’$1′, $referer);
to:
$query_terms = preg_replace(‘/^.*s=([^&]+)?.*$/i’,’$1′, $referer);
(here is the diff -u):

$query_array = preg_split (“/[\s,\+\.]+/”, $query_terms);
