bug#54173: 28.0.91; Training wheels for query-replace

[Juri Linkov]

> PS: Should we define 'p' as a synonym for '^' in 'query-replace-map'?

In my config I rebound '^' to 'C-r' to be like in isearch-mode,
so 'C-r' goes backward, 'C-s' forward, and 'M-e' is like
'isearch-edit-string':

  (define-key query-replace-map "\C-s" 'skip)
  (define-key query-replace-map "\C-r" 'backup)
  (define-key query-replace-map "\M-e" 'edit-replacement)
  (define-key query-replace-map "\M-\C-r" 'edit)
