Problem with ScreenSend using IPython>=5.0.0 and Tmux

[perellonieto]

I think there is a problem when sending code using Tmux and IPython>=5.0.0

Example

1. Create a Tmux session (e.g. tmux new -s test)
2. Open a python file with the following content

print('hello')

Then run the following commands

:IPython
:ScreenSend

Output with IPython==4.2.1 (Correct)
