Excel should allow undoing a command after saving (manual or autosaving). If
I save (or autosave does the save) but do not close my spreadsheet, I want to
be able to undo commands just like in Word and Visual Studio, etc.
At the lease, this could be an option controlled by the user. But right now,
there's no way to stop the undo buffer from being cleared when a save occurs.
