I think that to do this in general requires evaluating the defcustom at
compile time, which probably isn't the right thing.

emacs -batch -l admin/cus-test.el -f cus-test-opts all

will find these mismatches. I think it should be converted to an
(expensive) ert test, which would solve the problem for Emacs itself.
