Improved File::Spec::Win32->path [PATCH]

[Gisle Aas]

I noticed that File::Spec::Win32->path does not work the same as the
internal utility function we usually use.  This is a patch that makes
it work the same.

   - "." is always searched first on Windows
   - empty paths are ignored
   - paths can be quoted
   - %ENV is caseless
