23.0.50; CCL: Quited.

[Johan Bockgård]

$ emacs -Q -eval '(progn (fundamental-mode) (buffer-disable-undo) (insert-char 
?x 5000000) (goto-char (point-min)))'

Hit M-> and press and hold C-g. When the busy cursor disappears,
hit M-> again.

The text "CCL: Quited." is inserted at the end of the buffer (maybe
several times) and `C-h l' shows something like

M-> C-j C C L : SPC Q u i t e d . C-j C C L : SPC Q
u i t e d . C-j C C L : SPC Q u i t e d .
