Access control: allow editing of ALL nodes of a certain type

Haven't learned how to create a patch yet, apologies in advance...

I would like to allow a certain role to edit all nodes of a certain (CCK) type. On a site where you have a (role defined) group of people working together, f.e. moderating content, this would be very useful. I don't know a way of setting this up without either modifying content.module or allowing the role full access to ALL nodetypes... Hence the suggestion to add this to content.module :-)

I think it is this easy:
1. In content.module, function content_perm(), add:

$perms[] = 'edit all '. $name .' content';

2. In content.module, function content_access(), there is currently a snippet like this:

  if ($op == 'update' || $op == 'delete') {
    if (user_access('edit own '. $type .' content') && ($user->uid == $node->uid)) {
      return TRUE;
    }
  }

...the modified version would look like:

  if ($op == 'update' || $op == 'delete') {
    if (user_access('edit own '. $type .' content') && ($user->uid == $node->uid)) {
      return TRUE;
    }
    if (user_access('edit all '. $type .' content')) {
      return TRUE;
    }
  }

It would also be great to have access control on field level. It seems like there is work in progress though (http://drupal.org/node/78563), in the fieldgroup project (http://drupal.org/project/fieldgroup).
