patch

It's possible to redirect only stderr. This is enough for logs, while cmd will
use stdout. I can reproduce the problem with enter by setting an invalid
DISPLAY.

The problem of pressing enter is that we use VkKeyScanW in this case to find
virtual key code, which fails without a display driver. The attached patch
fixes that. We could consider better support for VkKeyScanW in null driver or
maybe not even go through display driver in cases like \r.
