bug#8720: 24.0.50; load-theme in .emacs makes it easy to inadvertently delete custom-set variables |

This is with Emacs revno 104332 on GNU/Linux.
Here's a recipe:
* Create a minimal .emacs file, containing the following:
-------------------
;; Load a theme - it doesn't matter which.
(load-theme 'sometheme)
(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.
'(user-mail-address "deng@randomsample.de"))
-------------------
* Start Emacs with that init file. Answer both questions "Really load?"
and "Treat this theme as safe in future sessions?" with 'y'.
* Exit Emacs.
* The .emacs file will now look like this:
-------------------
;; Load a theme - it doesn't matter which
(load-theme 'zenburn)
(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.
'(custom-safe-themes (quote ("79debafda48631fbb02f822cab5bb8d50df6e3f6"
default))))
(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.
)
--------------------
As you can see, the existing customization for user-mail-address was
deleted; in fact, every existing entry there will be deleted. I know
this can be fixed by putting the `load-theme' at the end of the .emacs
file, but this isn't mentioned in the doc-string and I'd still consider
this at least as unexpected behavior.
