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

[Erich E. Hoover]

Hi Piotr,

I just ran the widecharstring case on the testbot (
https://testbot.winehq.org/JobDetails.pl?Key=57989 ) and that seems to
return 0 instead of WEOF...  Are you alright with just adding this
test to demonstrate that it doesn't work the same way?  Failing test:
===
    buffer[0] = ' ';
    buffer[1] = '\t';
    buffer[2] = '\n';
    buffer[3] = '\n';
    buffer[4] = 0;
    ret = swscanf(buffer, formats, results);
    ok( ret == (short)WEOF, "ret = %d\n", ret );
===

Best,
Erich
