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.
