Not a bug, but intentional. To be a bug, it would need to
be documented to work, and it is not.
In Rgui other threads (e.g. a tcltk button) can be writing to the console
too. Implementing \r would be very complicated, and not worthwhile
(Windows has a perfectly good progress-meter widget!)

I tis nothing to do with Rterm, but terminal in which Rterm is running.
