... and just to make the point clear, N gets incremented with each undo,
and redo will pick the highest numbered ,,undo-N, and redo that only,
deleting the redone ,,undo-N dir.

You can have various undone changesets sitting around, and it's
perfectly safe to undo even good changes to quickly work on some other
bug for a while -- you don't need to worry about one undo overwriting
the previous one.  You can also move the ,,undo-N dir somewhere else in
case you'd like to revisit those changes later...

It's generally just very useful.
