That could be done, of course, but I'm pretty sure that this macro would
be used exactly once. I don't think we should have a general-purpose
macro to set up the lazy highlighting for arbitrary minibuffer commands,
because complex cases like query-replace will be rare, and in any case
we can't anticipate all special requirements.
Anyway, should I refactor my patch to use a macro?
Something else that could make 'query-replace-read-args' slightly
shorter is to define
(defun replace-regexp-function (delimited-flag)
(or replace-regexp-function
delimited-flag
(and replace-char-fold
(not regexp-flag)
#'char-fold-to-regexp)))
This function could be used in 3 different places in replace.el.

Right, a preview of the replacement text will also need some extra work.
This will probably involve some extension to
'isearch-lazy-highlight-update', making it even more complicated...
