Localizer support

I would like to use the node's locale in the path.
My first idea was something like that eg. /guides/[local]/title
That would be /guides/en/title and /guides/hu/title
After that I found out how can I make a better hack for this in the pathauto_node.inc.
I added this code in the node_get_placeholders():

if ($node->localizernode_locale=='hu') 
  $placeholders[t('[localguide]')] = 'leiras';
  else
  $placeholders[t('[localguide]')] = 'guide';

After that I can use the [localguide] placeholder on the node path settings page with my guide content type and my guides' path in English will be /guide/English_title and the Hungarian guides' path will be /leiras/Hungarian_title. This is very nice I think.
I know, this is a dirty hack but works for me ;-)
I wonder how can be make that better.
Basically I would like translatable placeholders.
