bug#29321: Isearch hit count

Regarding going to the last match, maybe simpler would be to have
these commands?

(defun isearch-beginning-of-buffer ()
  "Go to the first occurrence of the current match.
Move isearch point to the beginning of the buffer and repeat the search."
  (interactive)
  (goto-char (point-min))
  (isearch-repeat-forward))

(define-key isearch-mode-map "\M-s\M-<" 'isearch-beginning-of-buffer)

(defun isearch-end-of-buffer ()
  "Go to the last occurrence of the current match.
Move isearch point to the end of the buffer and repeat the search."
  (interactive)
  (goto-char (point-max))
  (isearch-repeat-backward))

(define-key isearch-mode-map "\M-s\M->" 'isearch-end-of-buffer)

where in isearch-mode 'M-s M-<' will jump to the first match,
and 'M-s M->' will jump to the last match.
