Beware: this changes the format of entries that can appear in the
buffer-undo-list, which has repercussions beyond primitive-undo, IOW it
can/will break other things such as undo-in-region and undo-tree.

Better use the (apply DELTA BEG END FUN-NAME . ARGS) form, which was
introduced specifically for use of such extensions.
