Yes. And that's why it's probably not a good idea to use 'undo' for
'redo' if the latter is not available. It's just unexpected. (Indeed,
why should there be a redo command at all if it's the same as undo?) But
maybe the error message could be improved so that it tells the user that
either 'redo' or 'undo-tree' should be installed (and activated).
