I think I fixed the original problem now.  I'm leaving the bug open
because the secondary issue of clobbering user customizations of
variables in the custom-delayed-init-variables list still needs
attention, perhaps some reasonable solution could be found.  For now,
I just added to the docs a warning against moving customizations into
the early init file that don't have to be there.

Thanks.
