How about this:
-- cut here ----------------------------------------------------------------
(defmacro setq-save (option value)
"Sets OPTION to VALUE if and only if OPTION is not already saved by
customize."
`(and (not (custom-saved-p ',option))
(setq ,option ,value)))
-- cut here ----------------------------------------------------------------
It might not be important to you but you might want to note that your `setq'
doesn't quite work the same as `setq' itself. `setq' takes multiple sym/val
pairs.
