    How would that be different from what `M-x customize-customized' does?

I tried looking for such an existing function, but I could not
remember its nam and missed it in the list of completions of
customize-...  Now that I see it, customize-customized might be what
he wants.  But not necessarily exactly what he wants.

Perhaps we could use something to customize all the options that have
non-default customizations, which is a little different from
customize-customized.
