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.

Logged In: YES user_id=80475 Confirmed for WinME/98. Also, the behavior changed from Py2.2 where on WinME/98, it returned the root directory. |

Logged In: YES user_id=92689 I didn't touch the Win side of os.listdir() (it already supported unicode strings), so I'm pretty sure it isn't. |

This may become important when switching to python 3.0...
When passed str(''), FindFirstFileA is called with "*.*".
But when passed unicode(''), FindFirstFileW is called with L"\\*.*" !!!
Attached patch fixes (and tests) the problem. It was developed on 3.0,
but applies on all versions.
