bug#1974: 23.0.60; gnus writes customize file

[trentbuck@gmail.com]

When using gnus, I find that it tries to write out my customize
preferences whenever I send a message.  This is bloody annoying, as
.emacs is version-controlled, and I do not *have* any
customize-managed preferences.

To stop gnus messing with my .emacs, I have the following in .emacs:

| (setq custom-file "~/.emacs.d/custom-sucks.el") ; this is never load-file'd

...but it's still annoying from an aesthetic standpoint.

The custom-sucks.el file written by gnus is:

| (custom-set-variables
|   ;; custom-set-variables was added by Custom.
|   ;; If you edit it by hand, you could mess it up, so be careful.
|   ;; Your init file should contain only one such instance.
|   ;; If there is more than one, they won't work right.
|  '(canlock-password "acc239ecbc3348a6f02d22b49ac0743957b28655"))
| (custom-set-faces
|   ;; custom-set-faces was added by Custom.
|   ;; If you edit it by hand, you could mess it up, so be careful.
|   ;; Your init file should contain only one such instance.
|   ;; If there is more than one, they won't work right.
|  )
