When i say that something is already fixed, i refer to NZWEI, since ZWEI has
only had very serious bug fixes (no new features) since the beginning of the
Undoableness does not fit well into the environment of a character editor,
because of the enormous overhead of undo saving every command, and the general
uselessness of undoing a self-inserting character, for example. It is intended
solely for giving a consistent way of recovering from gross changes to the
buffer, such as grinding it as text.
The problem with lisp machine software updates is NOT that new systems do not
automagically move themselves around while we sleep, it is that none of us has
enough time always to be generating those new systems.
