Package: Emacs
Version: 27.0.50

As brought up by Johan, the (apply ...) elements in buffer-undo-list are
"too powerful".  Even though BEG/END/DELTA are provided, with the
intention to make it possible for undo-in-region to handle those
entries, undo-in-region does not handle those entries.

The main problem being that undo-in-region (as well as
erc-update-undo-list, incidentally) needs not just to know which part of
the buffer is modified and with which DELTA, but it also needs to be
able to create a new entry to apply the same change at another
buffer position.
