Redirecting stdout to NUL (Windows) raises exception

[uranusjr]

I’m not sure if this is a bug in Pipenv. Crayon, Click, or even Python, but I need to log it somewhere.

Discovered #2527 (comment).

To reproduce:

λ pipenv >NUL

I believe any command that outputs to stdout (i.e. all of them) has this problem. Stderr works fine. I do not know whether Linux and macOS has this problem.

Seems to work on WSL, I assume it is a Windows-only problem, and is from an upstream library (likely Click).

Tracked in pallets/click#1065 instead.
