[PATCH 0/1] MR3647: msvcrt/tests: Make registry handle inheritable in test_invalid_stdin tests.

[Piotr Caban (＠piotr)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=55286

On Windows values passed in STARTUPINFO.hStdInput are preserved even if passed value is invalid. Because of that, newly created process was using garbage as standard input handle.
