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)
