Emacs 22.1 behaves similarly, but in Emacs 21.4, the cursor doesn't move and C-x = shows the first "b" at position 8. One more step to the right, the cursor moves to the second "b". It seems to be a bug that has been introduced in Emacs 22. > In fact, it seems you cannot really access the first "b" at > position 8 through cursor movements.
