Comment (by simonpj):

 This documents the instance-forall extension

 commit 6cf9b06fd193867bf4964eff4317479b9e25fca5

     User manual improvments

     - Document that you can use 'forall' in instance decls

     - Change the sections a bit, so that big sections (like
       lexically scoped type variables, pattern synonyms,
       implicit parameters) become more visible
