Package: Emacs
Version: 27.0.50
Save the file below and then open it as follows:
% emacs -Q ..../zones.el
C-M-f C-M-b ;; Move before first form
C-M-SPC M-; ;; Comment out first form
C-x u ;; Undo last change
When I do that, I see an error message in the echo area that says:
Changes to be undone by function different than announced
If I redo this after enabling the debugger on error, I get the following
backtrace:
Debugger entered--Lisp error: (error "Changes to be undone by function
different than an...")
signal(error ("Changes to be undone by function different than an..."))
error("Changes to be undone by function different than an...")
