PR #161 Breaks install of jupyter.

PR #161 breaks current installation of jupyter.
Creates a dependency conflict with prompt-tools & jupyter console.

ipython 7.0.1 has requirement prompt-toolkit<2.1.0,>=2.0.0, but you'll have prompt-toolkit 1.0.15 which is incompatible.

Replicate:
pip install jupyter

How can #161 break jupyter, when it just got merged and isn't on PyPi yet? 😕
I think IPython>=7.0 breaks the jupyter installation, since the jupyter-console version on PyPi (5.2.0, Aug 21, 2017 ) doesn't include #161.
If you run pip install git+https://github.com/jupyter/jupyter_console, all should work again (just testsed it in a fresh env).
I hope that helps

Maybe my mistake then.. all I know is all our tests installing jupyter began suddenly failing today and passed yesterday, and it referenced a dep incompatibility between jupyter-console and prompt-tools; and I see a PR involving prompt-tools here. Sorry for the trouble. 👍

Glad I could help 👍
