drush fra issue

On the site I'm rowking on when running drush @dev fra the function drush_features_revert() is being passed a nested array of module overridden / needs review feature names...

function drush_features_revert() {
  if ($args = func_get_args()) {
    var_dump($args);

returns:

array(1) {
  [0]=>
  array(4) {
    [0]=>
    string(8) "feature1"
    [1]=>
    string(8) "feature2"
    [2]=>
    string(8) "feature3"
    [3]=>
    string(8) "feature4"
  }
}

However, the code appears to require an array of strings, so it errors as follows:

explode() expects parameter 2 to be string, array given features.drush.inc:674          [warning]
array_shift() expects parameter 1 to be array, null given features.drush.inc:675        [warning]
array_shift() expects parameter 1 to be array, null given features.drush.inc:676        [warning]

Going back though debug_backtrace()'s output, it looks like the nested stucture is created in drush_features_revert_all() and passed to drush_invoke('features-revert', $features_to_revert);. I compared this function with the 1.x branch and noticed that that function basically replaces the following:

      foreach ($features_to_revert as $module) {
        drush_invoke_process(drush_sitealias_get_record('@self'), 'features-revert', array($module), array('force' => $force, '#integrate' => TRUE));
      }

This looks like it was changed in https://drupal.org/comment/7784057#comment-7784057 .

Changing back to the 1.x version of the code fixes the issue for me. Apologies if this turns out to be an issue on my end and should be tagged as support instead of a bug report.
