Oh yes, I confirm that there is a second bug: sys.stdin doesn't translate \r\n to \n, whereas sys.stdin is a text file.
Attached patch fixes both issues.
> Is it possible to add some tests for input()?
input() has already tests, but the bug was not detected because the test uses a mockup, not a subprocess. Moreover, I don't think that it is possible to test input() for the TTY case. It is not easy to test a TTY, especially on Windows.
If anyone knows how to reproduce the two bugs with a short Python script, I can try to convert it into a test.
> Also the patch uses tabs instead of spaces.
Yeah, I hate producing patches on Windows. Fixed in the new patch (prepared on Linux).
