Sounds as if somebody who did Windows at Microsoft had a good sense of humor to mimick the misnamed ENOTTY gotcha ;-) This is a great find, and a very impactful fix, as redirecting from /dev/null is how we try to force a "go interactive if talking to tty" program to realize that it is not talking to a tty. Thanks.
