2. The suggestion for "Save undo information" could say to use undo-tree, which already does that. According to undo-tree.el, it's already copyright the FSF, but it also says it's part of Emacs, which is surely false. The author is Toby Cubitt <
toby-undo-tree@dr-qubit.org>, and undo-tree's upstream is at

I can make these changes if they're deemed apt.
