The Emacs Lisp Reference makes that claim about major-mode hooks and,
less strongly, about minor-mode hooks. Certainly I'm not aware of such
a convention for non-mode hooks, like `occur-hook', and I don't think
it would make sense: hooks are set up at convenient moments, which do
not necessarily coincide with function boundaries.

Hey, it's funny: if I had proposed to move the code setting the
read-only and not-modified flags to before run-hooks, instead of
protecting the hook functions from changing the current buffer,
perhaps no one would have complained... :)
