Summary: os.listdir on empty strings. Inconsistent behaviour.

Initial Comment:
Behaviour tested in Python 2.3 (final) and 2.3.2 (final).
os.listdir('') and os.listdir(u'') have very different
behaviour across different OSes:

WinXP/WinNT:
os.listdir('') -- current dir (e.g. c:\python)
os.listdir(u'') -- root dir (e.g. c:\)

Win98
os.listdir('') -- root dir
os.listdir(u'') -- root dir

Redhat Linux 9.0
os.listdir('') -- OSError
os.listdir(u'') -- OSError

Particularly weird is the WinXP/WinNT behaviour that is
different between unicode and normal strings.

Suggestion for fix: Make os.listdir for empty strings 
always
raise an exception or always list the current working 
directory.

Confirmed for WinME/98.  Also, the behavior changed from
Py2.2 where on WinME/98, it returned the root directory.
