updated for version 7.4.399
Problem: Encryption implementation is messy. Blowfish encryption has a
weakness.
Solution: Refactor the encryption, store the state in an allocated struct
instead of using a save/restore mechanism. Introduce the
"blowfish2" method, which does not have the weakness and encrypts
the whole undo file. (largely by David Leadbeater)

Tests for undo file. Since this script is sourced we need to explicitly break changes up in undo-able pieces. Do that by setting 'undolevels'.
