But maybe it is safe to change the type of custom-file from defcustom
to defvar. I am only concerned about backward compatibility.
What happens if some users already have customized `custom-file' in
`custom-set-variables' and it will be removed from this list?
Perhaps, nothing bad. Moreover, the situation where `custom-file'
in `custom-set-variables' points to some file other than the file
where `custom-set-variables' is located, is invalid. It will cause
duplication of `custom-set-variables' list when Emacs saves customized
variables next time. So, not adding `custom-file' to the set of
variables in `custom-set-variables' is the right thing. `custom-file'
should be purely an internal variable (which is achieved with the
previous patch).
However, there is one situation when users have to deal with the
`custom-file' variable. When the user moves `custom-set-variables'
to a new location in another file, it's needed to tell Emacs about
this location, so the next invocation of `Custom-save' could write
customization to the new place. To inform users about that, the next
3 lines could be added to the comments of `custom-set-variables':
(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.
+ ;; When you move it to another init file, to tell Emacs about
+ ;; its new location for the current Emacs session, type C-x C-e
+ ;; at the end of this line: (setq custom-file buffer-file-name)
+ ;; For further Emacs sessions just put in your init file
+ ;; (load "custom-file.el"). There is no need to set `custom-file'
