I shouldn't have included the keyword argument; it only muddies the
waters here. The correctness of the output, what we expect to see in the
expanded form, is of primary concern.

When the value of `coding-system-for-write' is non-nil, only quoting it
twice survives expansion:
(setq coding-system-for-write ''raw-text)
(ert-with-temp-file myfile)
-> (let* ((coding-system-for-write 'raw-text) ...)
Otherwise, we get a free variable:
(setq coding-system-for-write 'raw-text)
(ert-with-temp-file myfile)
-> (let* ((coding-system-for-write raw-text) ...)
BTW, I'm not setting `coding-system-for-write' myself. That's being done
by the diagnostic tool.
