It can be allowed to: * undo a serious of continuous edits (with a non-continuous undo&undoafter) * redo an edit that was undone later (with reversed undo&undoafter). This is not the same as undoing the "undo action" because the "undo action" may be more than a single undo. ** For example: original: "123456789", edit A: "12x3456789", edit B: "1234567y89", redo A: "12x34567y89"
