open_shell not working with nano or vim

I am having this weird issue when I use open_shell() with nano.

The arrow keys do not seem to work right. When I use the up arrow, for example, nothing happens the first press and the second press gives me the letter ‘A’

This issue also appeared with vim as well.

I was able to capture this in motion when I use the showkey -a command below.

I am currently using Fabric3 1.14.post1

Historical note, this sort of thing works significantly better in Invoke and thus the upcoming Fabric 2. I routinely use vim via run() in that codebase.

As you read along in that issue history a potential, not-accepted fix was suggested that you could try. It’s just one line.

See https://github.com/fabric/fabric/issues/196, this is a known (and IIRC de-prioritized?) issue. I think it’s useful to have some of the problem documented though. I really find it annoying myself.
