28.0.50; diff-hl should use `repeat-mode' ... and not `smartrep'.

Commentary in `diff-hl' says

    ;; `diff-hl-mode' highlights uncommitted changes on the side of the
    ;; window (using the fringe, by default), allows you to jump between
    ;; the hunks and revert them selectively.

    ;; Provided commands:
    ;;
    ;; `diff-hl-diff-goto-hunk'  C-x v =
    ;; `diff-hl-revert-hunk'     C-x v n
    ;; `diff-hl-previous-hunk'   C-x v [
    ;; `diff-hl-next-hunk'       C-x v ]
    ;;
    ;; The mode takes advantage of `smartrep' if it is installed.

FWIW, `smartrep' is not part of GNU Emacs or GNU ELPA but available
elsewhere.  (I install it via MELPA)

Now, that `repeat-mode' is part of GNU Emacs, I think this dependency
on `smartrep' can be removed.

FWIW, this is what I have in my `.emacs'.

    (progn
      (defvar diff-hl--repeat-map
	(let
	    ((map
	      (make-sparse-keymap)))
	  map))
      (message "Installed %s" 'diff-hl--repeat-map)
      (cl-loop for
	       (cmd . key)
	       in
	       '((diff-hl-diff-goto-hunk . "=")
		 (diff-hl-revert-hunk . "n")
		 (diff-hl-previous-hunk . "[")
		 (diff-hl-next-hunk . "]"))
	       do
	       (define-key diff-hl--repeat-map key cmd)
	       (put cmd 'repeat-map 'diff-hl--repeat-map)))
