All I know is just now it changed my username to "jinni".
Good thing my eye caught it, only a few words back.

And was typing this:

 r r [self-insert-command]
 SPC SPC [self-insert-command]
 d [self-insert-command]
 e e [self-insert-command]
 t t [self-insert-command]
 e e [self-insert-command]
 c c [self-insert-command]
 t t [self-insert-command]
 C-n [next-line]
 C-n [next-line]
 C-n [next-line]
 C-b [backward-char]
 C-b [backward-char]
 C-b [backward-char]
 SPC [self-insert-command]
 C-o [open-line]
 C-o [open-line]
 C-. [flyspell-auto-correct-word]
 C-d [delete-char]
 C-/ C-/ [undo]
 C-h l [view-lossage]

I see my .emacs already has
;;Two flyspell keys too close to C-/ undo:
(global-unset-key (kbd "C-."))
(global-unset-key (kbd "C-,"))
etc. (But of course that is not good enough.)

And indeed I would have never hit either on purpose, only by accident.

When I really want to use flyspell-auto-correct-word I always use C-M-i,
not C-. .

And you know what,
no matter what I put into .emacs,

(eval-after-load "flyspell-mode"
  '(add-hook
    'flyspell-mode-hook
    (lambda ()
      ;;too close to C-/ (undo) and already on ESC TAB:
;     (define-key flyspell-mode-map [(control ?\.)] [])
     (define-key flyspell-mode-map (kbd "C-,") (lambda () (interactive)))
     (define-key flyspell-mode-map (kbd "C-.") (lambda () (interactive)))
     )))

I just can't unbind them.

They are un-unbinable.
