permissions admin UI sorts incorrectly

The permissions UI builds up a list of permissions grouped by module:

  foreach (og_get_permissions() as $perm => $value) {
    $module = $value['module'];
    $permissions_by_module[$module][$perm] = $value;
  }

It then does asort() on this. This is probably not what is intended, as it sorts the values. Here the values are arrays, and so (AFAICT) what happens is that the modules in the form are sorted by the number of permissions they each provide. That doesn't seem useful to me.

Perhaps this was meant to be ksort()? That would sort by module machine name.
