Group names with dots need to be quoted according to RF2822.

Michael, I tried it with this (ugly) patch:

                             }
+                            require_once 'Horde/MIME.php';
+                            $vars = get_class_vars('MIME');
+                            $listatt['name'] =
MIME::_rfc822Encode($listatt['name'], $vars['rfc822_filter'] . '.');
                             $results[$name][] = array('name' =>
$listatt['name'], 'email' => implode(', ', $emails), 'id' =>
$listatt['__key'], 'source' => $source);
                         }
                     }

But this resulted in inconsistent results when I expand names with ajax or
use the address book popup. Maybe you have a bright idea?
