AT the end (that is, after "You can disable the popping up of this buffer by adding the entry (undo discard-info) to the user option `warning-suppress-types'."), we might want to add something like the following (as rms suggested): " If you know what you are doing, and you don't want the buffer to collect undo information which uses memory internally, do M-x buffer-disable-undo, or (setq buffer-undo-list t)." Actually, we want people to tell us where they get these messages, so that we can learn about Emacs modes and facilities where we ought to turn off undo. So if we add something like this, we should add something urging people to send a bug report if they get such a message from any mode or facility built into Emacs.
