Document allowed syntax in WARNING and DEPRECATED pragmas
GHC accepts the following deprecation pragma:
{-# DEPRECATED f ["f is deprecated","use g instead"] #-}
f :: a -> a
f x = xThe deprecation message here is a list of strings. I didn't expect this to be allowed because https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#warning-and-deprecated-pragmas only shows examples where the deprecation message is a single string.
Are there other forms of deprecation message allowed by GHC?
