Provide a command to easily swap FROM and TO arguments in a query
replace operation.

(query-replace-read-map): New keymap.
(query-replace-read-from): Use new keymap to read from minibuffer.
(read-regexp-map): Inherit from 'query-replace-read-map'.
(query-replace-read-from, query-replace-read-to): Fix parameter
references in doc strings.
* etc/NEWS: Document the change.  (Bug#79835)

bug#80009

* doc/emacs/programs.texi (Hideshow): Update documentation.
* lisp/progmodes/hideshow.el (hs-hide-level-recursive): Rework.

* lisp/hi-lock.el (hi-lock-line-face-buffer, hi-lock-face-buffer)
(hi-lock-face-phrase-buffer): Use the new function
`hi-lock-read-regexp' to read font-lock patterns, mirroring
`hi-lock-read-face-name' used to read face names.  For end users,
all three functions now get the default value from the active
region, rather than just `hi-lock-face-buffer'.
(hi-lock-read-regexp): Extract font-lock pattern reading
functionality from `hi-lock-face-buffer' into this function, to
mirror how faces are read with `hi-lock-read-face-name' and to
promote reuse.  (Bug#79976)
