bug#3136: 23.0.92; Customized variables include state string

[Cameron Horsburgh]

When I change a string variable using the customize interface, the
line after the entry point for the string is included in the
string. So, customising the variable 'twitter-username' to 'fred' leads to:

,----
| 
|  '(twitter-username "fred
|    [State]: EDITED, shown value does not take effect until you set or save it.")
| 
`----

This behaviour has occurred for variables in several modes I have
tried to customise and is readily reproducible.

I can't reproduce this.  Please provide a precise recipe for reproducing
this, starting with `emacs -Q'.

Thanks for your reply. Here's a blow by blow reproduction of trying
this with emacs -Q.

I move my existing .emacs out of the way, stop all running emacs
processes and call emacs -Q. Then I run M-x customize-variable. I need
to choose one that can be set to a string but has no initial value,
because I can change existing values without the problem behaviour
occurring. A good candidate is fill-prefix:

M-x customize-variable fill-prefix

I choose the option to set the variable to a string. I am given an
area to type my customisation. However, the input area also appears to
include the line immediately following, which refers to the state of
the variable. I enter a string (say, NonsenseString) into the
appropriate place and save with C-x C-s.

Then I look at my .emacs file:

C-x C-f ~/.emacs 

and I find:

,----
| 
| (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.
|  '(fill-prefix "NonsenseString
|    State: EDITED, shown value does not take effect until you set or save it."))
| (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.
|  )
| 
`----

I should also add that I have been able to follow this recipe in an
xterm and in the GTK GUI version of emacs. Thanks for your time in
helping get to the bottom of this!

Looks like my 2009-03-24 changes to wid-edit.el are to blame.
