bug#53126: 29.0.50; [PATCH] Lazy highlight/count when reading query-replace string, etc.

[Juri Linkov]

>> Could you please split it to more logically separate patches?
>>
>> 1. a patch that removes checks for 'isearch-mode (null 
>> isearch-message-function)'
>>    and adds '(setq-local isearch-lazy-count nil)'.
>>    It could also contain more changes in comint.el etc
>>    from your earlier patch from 14 May 2021.
>>
>> 2. a patch that adds and runs 'lazy-count-update-hook'.
>>
>> 3. a patch with minibuffer-lazy-highlight feature in isearch.el.
>>
>> Then what will remain to do is to decide how it would be better to activate
>> the minibuffer-lazy-highlight feature.
