Tags spread across the whole file were adjusted by one or tow spaces. Probably I just accidentally hit C-u before setting a tag to a new heading by C-c C-q. Of course, I did not noticed it immediately. I managed to create a commit with real changes without noise due to tags realignment. However I would like to prevent similar issues in future. I can add a prompt for a particular argument of a function by (defun nm-safe-org-set-tags-command (&optional arg) "Call `org-set-tags-command' requiring to confirm realigning of all tags." (interactive "P") (cond ((and (equal '(4) arg) (not (yes-or-no-p "Realign all tags? ")))) (t (call-interactively #'org-set-tags-command)))) (add-hook 'org-mode-hook (lambda () (define-key org-mode-map (kbd "C-c C-q") #'nm-safe-org-set-tags-command))) The function can be made a bit smarter by adding minimal file size threshold. However almost certainly there are more function "destructive" in a similar way. Is there a more general approach to make commands safer in respect to global modifications?
