emacs-29 8e9783b4ce: Rebind in read-regexp-map ‘M-c’ to ‘M-s c’ compatible with search-map

[Juri Linkov]

branch: emacs-29
commit 8e9783b4ce42122a8670f16f21a73597a226b674
Author: Juri Linkov <juri@linkov.net>
Commit: Juri Linkov <juri@linkov.net>

    Rebind in read-regexp-map ‘M-c’ to ‘M-s c’ compatible with search-map
    
    Also it's compatible with 'M-s c' (isearch-toggle-case-fold)
    used during Isearch.  Also makes possible to use the global keybinding
    'M-c' (capitalize-dwim) in the minibuffer.
    
    * doc/lispref/minibuf.texi (Text from Minibuffer): Rename ‘M-c’ to ‘M-s c’.
    
    * lisp/replace.el (read-regexp-map): Rebind ‘M-c’ to ‘M-s c’ (bug#60741).
    (read-regexp-toggle-case-fold): Rename from read-regexp-toggle-case-folding
    to more standard name.
