Note that you reverted the patch direction.

You should also take an extra-files argument, e.g. to add custom.el or
other elisp files that init.el might refer to.

Also, I'm not certain if "scheme-file" is the right primitve here –
Emacs Lisp does differ from Scheme, e.g. in keyword syntax among
others.
