[resend] shell32: for FO_COPY, if the destination is an empty string, SHFileOperation should use the current directory.

Hi Lionel, one minor comment on your patch:

+    /* If the destination is empty, SHFileOperation should use the
current directory.
+       See bug #13394. */

There's no need to quote the bug to explain why your code is doing
what it's doing.  The test case is sufficient.
