Code example making case for missing newline in wine printf when multibyte
string is printed

Wine's printf is missing newline when "Multibyte string пукпукпук\n" is
supplied to printf(). Attached code is a test-case reproducing the bug. When
same binary exectued on windows, or same code compiled for- and executed on-
linux - all goes fine. Only when executed under wine newline is missing. It
results in that printed string shares same line with next PS1 prompt here is
screenshot illusrating the problem (FIG1):

Note that extra newline in wine cmd.exe is missing.

Here is refference windows screenshot (FIG2) showing where this extra newline
should be:

Known possible workarounds for this problem:

* add '\r' before '\n'
* use only ascii (non-multibyte) characters in printing string
* use WCHAR instead of wchar_t
* use wprintf(L"%ls\n"~ instead of printf("%s"~

But all this workarounds are just a sideways. I hope that there is some real
solution.

Thanks.
