I've just installed on the trunk a patch which fixes it.

Hello,

according I brief discussion on help-gnu-emacs, this appears to be a bug in
Emacs 22:

(defun test ()
  (interactive)
  (insert "a")
  (undo-boundary)
  (insert "b"))

If I do M-x test, I get:
ab
  ^

Then, if I undo once in Emacs 22, I get:
a
^

What I was expecting (and what happens in Emacs 21):
a
 ^


Also note:
