apachesolr_strip_ctl_chars() also on $document->path

While indexing my document base, I stumble upon a document with a control char (8) in the path (don't ask...)

I had to modify the apachesolr_node_to_document() function as in the code below (sorry not providing a patch, but I'm not currenlty lined up with *latest* CVS (but I always keep an eye on that)... In need to test Solr 1.4 first)

...
      if ($output && $output != $path) {
        $document->path = $output;
      }
...

became

...
      if ($output && $output != $path) {
        $document->path = apachesolr_strip_ctl_chars($output);
      }
...
