Currently, FilePath is an alias for String.  Changing FilePath to a real
type will break programs because there is no constructor for FilePath
currently, so everyone uses String.  And Haskell doesn't auto-coerce, so you
would need to use a typeclass and separate String and FilePath instances for
compatibility.

(On the other hand, this might be a good idea anyway; another instance that
would be useful would be [Word8].)
