Well, even in wordprocessors there are some operations like "save" (or
"print" :-) that  can't be undone.  Some apps refuse to undo the save
(word?), and some just exclude the save from consideration and undo
the previous action (emacs/gimp).  We tend to run into those
boundaries earlier because bzr interacts extensively with the
filesystem and other programs rather than working just  working on its
own data model.
