I'd be surprised if `setq' is the right answer (it's probably more like
customize-set or something along these lines), and it deserves
a `message', but other than that I guess it's OK.
We used to actually save, which resulted in overwriting the user's
custom-file with a mostly empty file, so we fixed it by signalling an
error, but I guess that just outputting a message and not saving is
good enough.
