'pyreadline' on windows now required starting 4.1.0 ?

[stonebig]

Christoph Gohlke doesn't advise it ((unstable, deprecated), a ctypes-based readline for Windows.), and it was not required before.

==> isn't there any other solution than this c356a77 ?

It has always really been a requirement on WIndows, we just forgot to list it as a dependency before. The experience without it would be terrible - no tab completion, no command history, no colours and potentially ugly escape codes visible when it tries to use colour.

We have a plan to move away from pyreadline - see ipython/ipython#9118 for the start of that - which will hopefully be in place for 5.0 of both ipython and jupyter_console. But for now, yes, pyreadline is required.
