Well, that's the convention these days, certainly... but it's not
necessarily always very useful. It's admittedly hard to do it any other
way *if* you've subsequently changed the object to which a particular
action in the undo list applies-- but quite often you haven't.
For example, in a word processing app, if I format a paragraph a
particular way, go away and edit some other part of the document, then
decide I want that paragraph back the way it was, there's no reason on
earth why I should be forced to undo everything I've done since... and
there's many a time I've cursed an application for forcing me to do just
Wouldn't it be wonderful if an action in the undo list remained
independently reversible throughout its "undoable" lifespan (i.e. in the
simplest case, until you subsequently changed the object to which it
applied)? Sure it's a non-trivial problem, but that's what we're here
