I would say that we should ensure that Emacs doesn't crash, but it should
ignore all non-symbol values, like most other configuration variables do.

Allowing strings would make the code more complex and it would make testing
harder etc, without giving us any advantages.

The important thing, however, is that the documentation clearly states that
a symbol should be used.
