You need to use `add-to-invisibility-spec` before that works. E.g.:
(add-to-invisibility-spec 'dummy)
that's because of a quirk of the way we treat `invisible` and the
`buffer-invisibility-spec`.
Stefan
PS: To fix this quirk, we should change buffer-invisibility-spec's
default value to nil (or `(t)`, maybe) instead of t.
