I don't think any redo mechanism works that way.  Once you actually
change anything, the redo possibility is lost.

The way redo works, e.g. in `joe' editor is that you can press undo n
times, then move around all you want, and then press redo m times (m
<= n) to undo the undo itself.

In Emacs when you start moving around, the undo-s are recorded as just
a set of changes to the buffer, which is often annoying.

Can you please name me an editor whose undo/redo works as you
described above?  I'd like to try it.
