What you're talking of is a general hook mechanism which is being
considered for pacman as it would not only simplify this case, but
also allow us to update man-db, update the icon cache and mime cache
etc. automatically, after all the packages in a pacman transaction
have finished installing.  Some initial discussion on this has taken
place [1] [2], but I don't think anything concrete has happened.
