[PATCH] msvcrt: Fix fscanf return when EOF is immediately after an end of line.

[Piotr Caban]

Hi Erich,

The implementation part of the patch doesn't look right. I think that it 
should be fixed by %s format reporting error when there's no characters 
to read.

I'm attaching a diff (generated on top of your patch) that shows the 
problems.

Also please use only tests on strings (sscanf) or handle file creation 
failure.

Thanks,
Piotr
