variables in a custom group (recursively), or which group a custom
variable belongs to. I would have thought the latter would be a symbol
property, but it isn't.
Obviously `customize-group' must be able to find out, but when I

Right now I'm doing this, which I guess works okay, but it seems a bit hacky:
(when (and (custom-variable-p sym)
(push sym target-syms))))
