I use "occur" on big (> 100 MB) text-files quite often. While doing the very nice filtering, emacs regularly, but not always, output a message about the undo-information that prompts me to give it a yes or no aswear. I cannot exactly remember the wording, but yes means "yes, go along and drop the ability to undo the changes in the *occur* buffer".

Could this kind of behaviour be avoided? I can see no occasion when I would like to undo in an *occur*-buffer.

Then you should:

(add-hook 'occur-mode-hook (lambda () (setq buffer-undo-list t)))

I have been using the cvs-versions for quite some time and this is not new.
