Right.
It's because your init file changes the faces but does not save those changes or
cancel them. Then, when you save changes with C-x C-s, that saves the faces you
changed.
You want to either (a) do what you do now: redefine the faces after loading your
`custom-file' each time or (b) just tell Customize that the faces have _not_
been changed (even though they have), before hitting C-x C-s. That is, just
tell Customize to ignore your changes.
For that, you can just add those faces to option `customize-customized-ignore'
(user preferences to ignore in `customize-customized'). For that you will need
to load library cus-edit+.el.
http://www.emacswiki.org/emacs-en/download/cus-edit%2b.el
If you do not want to do that, then you can use code like this in your init
file, just after setting the faces the way you want:
(face-spec-set THE-FACE (get THE-FACE 'face-defface-spec) 'reset)
That should work. This should also do the trick, as an alternative:
(put THE-FACE 'saved-face nil)
(put THE-FACE 'saved-face-comment nil)
(put THE-FACE 'face-comment nil)
(put THE-FACE 'customized-face-comment nil)
Here's another tip: Get in the habit of using the `State' menu for the
particular option or face that you've changed, to save its changes, instead of
using C-x C-s, which saves all changes.
If you are worried about not catching some unsaved changes, you can use `M-x
customize-unsaved' before you quit Emacs. You can even put that on
`kill-emacs-query-functions':
(add-hook 'kill-emacs-query-functions
(lambda () (ignore-errors (customize-unsaved))))
Then, when you exit Emacs, if you have any unsaved changes, Customize will open
to them, so you can decide whether you want to save them. Any faces or options
listed in option `customize-customized-ignore' (cus-edit+.el) are ignored for
this - any changes to them are silently ignored.
