Summary: Tkinter is not working on trunk (2.6)

Initial Comment:
Hello. I tried to run tk app on trunk, I got following error.

///////////////////////////////////
// Code

import Tkinter as Tk
root = Tk.Tk()
label = Tk.Label(root, text="Test")
label.pack(fill=Tk.BOTH, expand=True)
root.mainloop()

///////////////////////////////////
// Error

Traceback (most recent call last):
  File "\debug.py", line 6, in <module>
    label = Tk.Label(root, text="Test")
  File "e:\python-dev\trunk\lib\lib-tk\Tkinter.py", line 2464, in __init__
    Widget.__init__(self, master, 'label', cnf, kw)
  File "e:\python-dev\trunk\lib\lib-tk\Tkinter.py", line 1930, in __init__
    (widgetName, self._w) + extra + self._options(cnf))
_tkinter.TclError: invalid command name "label .12893496 -text Test"


This is due to the change revision 55504 (Stop using METH_OLDARGS)

Currently, lib/lib-tk/Tkinter.py uses this convension

1929:        self.tk.call(
1930:            (widgetName, self._w) + extra + self._options(cnf))

...passing argument as single tuple. METH_OLDARGS treats this as same as 

        self.tk.call(
            widgetName, self._w, *(extra + self._options(cnf)))

So it was working, but now METH_VARARGS, it doesn't expand single tuple as arguments.

Maybe do we need to check all tk.call and apply patches like this?
