 From what I can gather from my research, the current behavior is not 
POSIX compliant then.  I had difficulty finding documentation regarding 
POSIX, paths, split and root directories, but what I did find leads me 
to believe that in the case of root directories, the root directory 
should be returned as the first element, and the second element should 
be empty.

Using Python's "posixpath", for example, we get this:

 >>> import posixpath
 >>> path = "/"
 >>> posixpath.split(path)
('/', '')

It's possible this is incorrect, but I couldn't find any hard 
documentation to refer to.  Do you have a link?

In any case, posixpath does not return the expected result on Windows 
(nor am I even sure if POSIX path rules apply to Windows paths).

 >>> import posixpath
 >>> path = "C:\\"
 >>> posixpath.split(path)
('', 'C:\\')

On Windows File.split should just return [PathRemoveFileSpec(), 
PathStripPath()].
