Win32/Process.inc: [PR8527] Process::FileDescriptorIsDisplayed(fd) should not check by FILE_TYPE_CHAR. It must be better to check it with Console API.
The special file "NUL" is FILE_TYPE_CHAR with GetFileType(h). It was treated as display device and discarding output to NUL had failed. (eg. opt -o nul)
