      If I understood correctly, the only really
    safe thing to do when confronted with the prompt is answer "Yes",
    because otherwise you risk a crash, after which you can not undo the
    last command anyway.

That reasoning is based on the idea that the smallest risk of a crash
outweights anything else.  I don't make my judgments that way.  I
usually answer no to these questions.

there was indeed a bug where Emacs generated lots of undo info during
a single command and crashed, and the only fix I could see was to
discard the undo info.  So I don't think turning off the question is a
good default.

However, we could probably substantially increase the size threshold.
If we multiply it by 10, it might still be good enough to prevent a
problem, but it might rarely be encountered when there is no problem.
