MultiProgress bar flickers#2

[inv2004]

I did another try of indicatif 0.13.0, and found that as soon as I only one ProgressBar into MultiProgress it starts to flicker the same I described in #42.

Please submit a code reproducing the problem and your environment

windows-10. conemu.

It is just a bit modified example/multi.rs
If I change ranges for 10k 100k 10k - it stops flicker.

I got the same flickering problem using MultiProgress bar with thread pool. But I don't observe such behavior on Linux.
The code is almost the same as in the example.

[Deniskore]

    let m = MultiProgress::new();
    m.set_move_cursor(true);

Solves the problem with flickering
