bug#9337: 24.0.50; M-x customize-create-theme not behaving as expected

[Jambunathan K <kjambunathan@gmail.com>]

Summary:

M-x customize-create-theme followed by "Save Theme" is not dumping all
my face configurations.

Details:
1. Start emacs for regular use.
2. M-x customizec-create-theme RET (when prompted say y)
3. Note that it dumps face definitions that are currently active. (My
   face definitions belongs to pre-theme era and is handcrafted and
   saved through the regular customize interface)
4. Make no changes to the offered faces and click on "Save Theme"
5. Visit the theme file so created.
6. Note that the theme file contains ZERO face definitions.

Here is a dump of M-x list-command-history RET

I expect to see all my face configurations saved in the above
file. Unfortunately I see ZERO face definitions. FWIW, I use a
green-on-black as my default face along with other configurations. So I
do have local changes to my faces.
