Not at all -- thank you for writing it!

While I have you, though: when you say "Also, it is not necessary
separately to remember editing operations in undo records, in order to
preserve precise buffer history", what is meant there?  Without having
looked at the code, my guess is that you're contrasting the persistent
buffer implementation of undo, which doesn't need to remember editing
operations, with the "ordinary" buffer implementation, which does --
but I could be wildly off.

Thanks,

Christophe
