 The GHC docs for GeneralisedNewtypeDeriving at
 (https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html
 #generalised-derived-instances-for-newtypes) suggest British spelling
 should be accepted, and indeed it's the preferred spelling in the docs.
 However GHC 8.2 throws an error. I haven't tested this against HEAD so if
 it's fixed there please feel free to close.

 I know this is a bit picky but it's caught me out a few times and I
 couldn't see it previously reported (I may have missed it though).
