Then nil isn't really a coding system, but just a value that some
coding system related functions happen to interpret in a certain way.
Ah, it turns out that I was confused because I hadn't read the
documentation for `coding-system-p' carefully enough:
Return t if OBJECT is nil or a coding-system.
Though, I think it's a bit odd for a predicate called
`coding-system-p' to return t for an object that is _not_ in fact a
coding system.
