Comment (by simonpj):

 My idea was to make `pprIfaceDecl` behave like `ppr_ty_thing`. The former
 is used only when displaying the contents of interface files, so it's ok
 for it to change a bit, particularly if the change is for the better.

 I think there will be bumps in the road, but we'll find them.
