capsys.disabled for stdin

I'm using pytest 3.0.4

Currently, using capsys.disabled prevents the capturing on stdout. But it does not do anything for stdin, which is also important for my use. (specifically, I want to be able to use input().)

Adding the -s command line option works, but I'd like to do it programmatically in a test. Ideally, you'd get something like this:

    def test_capfd_thing(capfd):
        print("this won't be visible")
        with capsys.disabled():
            print("this will be visible.")
            s = input("Type the word potato:")
            print("you said: "+ s)
        assert 'potato' in s

I'm not sure whether only disabling the capturing of stdout is expected behavior (in which case I would like a way to do what I'm doing above) or a bug.

Start from the capsys.disabled entry point and the -s command-line behavior described in the issue, then inspect the capture implementation and related tests. Verify how stdin is handled while stdout capture is disabled; done means a test can use input() interactively inside the context while normal capture remains unchanged outside it.
