better redirection after deleting a thread

when you delete a thread (permanently) you have the option close and refresh
-edit- when deleting from within the thread.-edit-

Of course there is nothing to refresh to. So you get the message
This message has been deleted or moved, and therefore not available.


go back?
but when permanently deleting a thread it is not necessary to refresh.. you can directly go back to the topicslist where the topic was, where you are also send to when you hit the Go Back link.

So my suggestion is that when permanently deleting a thread the link in the pop up after deleting should be close and go back.
