Passing an empty string isn't an argless call.

If you want os.listdir to be similar to ls, os.listdir() should be
equivalent to os.listdir(".") (currently the string argument is
required). 

And for an empty string a brief test shows that ls with an empty string
as argument behaves just like os.listdir("") (both on GNU/Linux system):

$ ls ''
ls: : No such file or directory

>>> os.listdir("")
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OSError: [Errno 2] No such file or directory: ''
