Before this change, the following invocation would not work ``` $ http http://neverhttps.com <&- ``` The "<&-" at the end closes the stdin fd. Specifically, it would fail with ``` ... File "/home/mgsloan/.local/lib/python3.6/site-packages/httpie/context.py", line 26, in Environment stdin_isatty = stdin.isatty() AttributeError: 'NoneType' object has no attribute 'isatty' ``` This can occur when httpie is being programmatically invoked, and may as well be supported.
