GetFileAttributes cannot handle paths with trailing dir separator. The
current [l]stat implementation calls GetFileAttributes twice if the path
has trailing slashes (first with the original path passed to [l]stat, and
and a second time with a path copy with trailing '/' removed).
With Unicode conversion, we get the length of the path for free and also
have a (wide char) buffer that can be modified.
Remove trailing directory separators before calling the Win32 API.
