How to 'un-sign' a key?

[Joel C. Salomon]

Folks,

I foolishly signed a key I had not verified well, and the signed version
is on a keyserver.  How can I unsign it?

I have tried the following (changing the key ID to 0xDEADBEEF):

> C:\Users\chesky>"c:\Program Files\GNU\GnuPG\gpg.exe" --edit-key 0xDEADBEEF
> gpg (GnuPG) 1.4.9; Copyright (C) 2008 Free Software Foundation, Inc.

>                      trust: undefined     validity: full
> [  full  ] (1). Mister Magoo <mister at magoo.not>
>
> Command> revsig
> You have signed these user IDs on key DEADBEEF:
>      Mister Magoo <mister at magoo.not>

That’s not all that’s supposed to happen, is it?
