I don't see how that's a correct solution in the face of arbitrary
regional undos and prefix args. Would you have the redo records
resulting from regional undos still map to t in the undo-equiv-table?
How does your solution account for redo records that undid several
because of prefix-arg? undo-equiv-table only maps to the change group
after the last undone record without information about the (1-
prefix-arg) others.
My proposition accounts for these considerations and I think is
correct. If not I hope to find out when I start hacking it.
