Re: query-replace-regexp does not use isearch-open-invisible properties

[Richard Stallman]

    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.

That seems like a good idea to try.  If the results are not ugly
(or not much more so than the present code), we could install it.

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

People are proposing a few changes in the meaning of
post/pre-command-hook.  Someone suggested making the Emacs servers run
it.

I would feel better about these changes if we could state a new simple
description of when the hooks should be run.  Perhaps that new
description would call for a different name too.

When we have that new purpose and name, perhaps we should make a new
hook and leave post/pre-command-hook unchanged.  Or perhaps make them
aliases.  We need to see what the new name and purpose are, to judge
that.
