Good advice. I did have to read the sentence a couple of times to be
absolutely sure you were telling me to use "print -r".
But I would still expect some change (a backspace should change to "\b" when
using "print", or "\b" should change to "\\b" when using "print -r").
And there is absolutely none as far as I can tell. And I think that's odd.
