node_style_return_vars drops template.php $vars

hi

after i have inserted the node_style_return_vars line into my template.php the $vars set with $region vars are lost. check out the following example i'm using:

function _phptemplate_variables($hook, $vars = array()) {
  switch ($hook) {
    case 'page':

      // Load region content assigned via drupal_set_content().
      foreach (array('example_region1','example_region2') as $region) {
        $variables[$region] = drupal_get_content($region);
      }
      break;
  }

  // node_style module is installed and active
  if (function_exists('node_style_return_vars')) {
    return node_style_return_vars($hook, $vars);
  }
  else {
    return $vars;
  }
}

it looks like there are some variables naming bugs in the node_style_return_vars function. I have corrected them and the following fixes this bugs:

/**
 * Returns a PHPTemplate variables array based on $hook. Called from node_style.inc.
 *
 * @see _phptemplate_variables
 */
function node_style_return_vars($hook, $vars = array()) {
  global $node_style;

  $scheme = $node_style['variables'];
  if (isset($vars['node']) && isset($scheme['display'][$hook])) {
    foreach ($scheme['display'][$hook] as $var) {
      $vars[$var] = '';
    }
  }
  if ($hook == 'page') {
    // Rather than appending to "head", append to styles, thereby allowing for
    // overrides of existing stylesheets.
    $vars['styles'] = $vars['styles'] . trim($scheme['misc']['head']);
  }

  return $vars;
}

here are the diffs:

are you able to fix this soon, please?
