Following a discussion on help-gnu-emacs

https://lists.gnu.org/archive/html/help-gnu-emacs/2017-11/msg00415.html

I request to replace the function find-dired-sentinel by something
like the following that will sort the output of find
lexicographically.  I have tested that the function below works for me.
Yet there might be corner cases I do not know about where it might fail.

(defun find-dired-sentinel (proc state)
  "Sentinel for \\[find-dired] processes."
  (let ((buf (process-buffer proc)))
    (if (buffer-name buf)
	(with-current-buffer buf
	  (let ((inhibit-read-only t))
	    (save-excursion
              (save-restriction
                (widen)
                ;; `find-dired-filter' puts two whitespace characters
                ;; at the beginning of every line.
                (narrow-to-region (point) (- (point-max) 2))
                ;; Sort file names lexicographically.
                (sort-subr nil 'forward-line 'end-of-line
                           (lambda ()
                             (buffer-substring-no-properties
                              (next-single-property-change
                               (point) 'dired-filename)
                              (line-end-position))))
                (widen)
                (let ((point (point-max)))
                  (goto-char point)
                  (insert "\n  find "
                          (substring state 0 -1) ; omit \n at end of STATE.
                          " at " (substring (current-time-string) 0 19))
                  (dired-insert-set-properties point (point))))
              (setq mode-line-process
		    (format ":%s" (process-status proc)))
	      ;; Since the buffer and mode line will show that the
	      ;; process is dead, we can delete it now.  Otherwise it
	      ;; will stay around until M-x `list-processes'.
	      (delete-process proc)
	      (force-mode-line-update))))
	  (message "find-dired %s finished." buf))))
