Hi Corinna,

Hmm, even after cbb9849fa76f1dbe6c66d91b68d9a10f46f1ba69,
it does not work in my environment.

But ok, f992ae6f4da99b6a200cfc146b96e8e921ca1e70 works.

Using f992ae6f4da99b6a200cfc146b96e8e921ca1e70, the problem
you had pointed out has been regenerated. Same problem can
be regenerated with a simple test case below.

#include <windows.h>

int main()
{
	HANDLE hCons;
	DWORD n;

	hCons = GetStdHandle(STD_OUTPUT_HANDLE);
	WriteFile(hCons, "AAAA\n", 5, &n, NULL);
	WriteFile(hCons, "BBBB\n", 5, &n, NULL);
	WriteFile(hCons, "CCCC\n", 5, &n, NULL);
	CloseHandle(hCons);
	return 0;
}

This is caused obviously by the patch I had proposed.
Post processing, in which \n is converted to \r\n, was in
the read process previously, so it had effect to the test
case above.

However, now the post processing is in the write process,
so it does not have effect against direct WriteFile() to
the pipe.

Unfortunately, I have no idea for the moment....
