[ This is not an answer, but anyway... ]

If you check out the CVS repository, you'll see a new minor-mode
`reveal-mode' which does basically the same as isearch-open-invisible
except that it does it all the time rather than only from isearch.
I use it with outline-minor-mode (I do (hide-sublevels 1) in
outline-minor-mode-hook and then I don't need any outline-minor-mode
command any more: text gets opened/closed as I move around the buffer).

Sadly it doesn't work for query-replace because query-replace uses
`read-event' when querying the user which does not run post-command-hook
(where reveal-mode hooks itself).

Maybe query-replace should explicitly run pre/post-command-hook?

Of course an alternative would be to change query-replace to not use
`read-event' but to do what isearch does: use overriding-terminal-map or
a recursive-edit so as to use the usual command loop which would (as
a side-effect) run post/pre-command-hook.
