commit https://github.com/vim/vim/commit/2cab0e191055a8145ccd46cd52869fbb9798b971
Author: Bram Moolenaar <Bram@vim.org>
Date: Thu Nov 24 15:09:07 2016 +0100
patch 8.0.0096
Problem: When the input or output is not a tty Vim appears to hang.
Solution: Add the --ttyfail argument. Also add the "ttyin" and "ttyout"
features to be able to check in Vim script.
