OK. I have moved the customization of these three options to my
org-init.el. Instead of the simple setq, I used
customize-set-variable, because it respects the respective custom-set
property (if it exists).
There remain two problems:
1. customize-set-variable does not do type checking. I have just
tested it by setting org-agenda-files to 42 (an integer).
set-variable does type checking, but does not respect any custom-set
property. How can I elegantly combine both? And shouldn't elisp
provide a convenient command for this?
2. If I forget that these options are changed manually (Emacs does
not warn), and configure them via customize, then the new value will
be added to the custom-set-variables form with static values. This
has two problems:
1. It will have static values.
2. Since org-init.el is called after the custom-set-variables
form, the values set in the form will be overwritten.
