Thanks. Can you tell me if the workaround below (calling change functions manually) is
correct/safe for emacs versions where this is not fixed? It's a function that
non-destructively replaces region contents.
(defun my-replace-region (beg end text)
"Replace region BEG END with TEXT.
As far as possible the replacement is non-destructive."
(let ((source (current-buffer)))
(with-temp-buffer
(insert text)
(let ((replacement (current-buffer)))
(with-current-buffer source
(save-restriction
(widen)
(narrow-to-region beg end)
(let ((inhibit-modification-hooks t))
(run-hook-with-args 'before-change-functions beg end)
(replace-buffer-contents replacement)
(run-hook-with-args 'after-change-functions beg
(+ beg (length text)) (- end beg)))))))))
