Subject: Addresses #174 Neovim Error (#197)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/e196180a0dec49549565850239831d4420464623?ds=sidebyside;pf=etc

Addresses #174 Neovim Error (#197)

Neovim uses stdout for `msgpack` communication and the `subprocess` call for `virtualenv` was leaking that stream. Fix is to attach to a `subprocess.PIPE`.
