Role assignment via path doesn't work

I know that's development version, but maybe following issues can be useful:

Followed existing code during inserting the user checking only first part of the path (arg(0)):

function autoassignrole_user($op, &$edit, &$account, $category = NULL) {
  switch ($op) {
    case 'insert':
      $page = db_fetch_object(db_query("SELECT rid FROM {autoassignrole_page} WHERE path = '%s'", arg(0)));
...
      $edit['roles'] = NULL;
    break;

And at the end, even if some role has been assigned, it's deleted anyway (NULL).
I.E. when I have set path to 'user/register', it's checking only 'user' path, so query return empty array.

The right code should be like this:

      $path = substr(request_uri(),1);
      $page = db_fetch_object(db_query("SELECT rid FROM {autoassignrole_page} WHERE path = '%s'", $path));
...
      //$edit['roles'] = NULL; // delete this line
