Summary: tk_focusNext() fails

Initial Comment:
Calls to the widget method tk_focusNext() fail with

"unsubscriptable object" error. Looking at the Tkinter.py 

code for the routine shows this statement:



name = self.tk.call('tk_focusNext', self._w)



(line 433)



which used to return a string in 2.2 but now returns

a "cmdName object". When this is passed to 

self._nametowidget(name), it fails when it tries to

subscript name (line 1006) since the object does

not support indexing. Perhaps str(name) or

name.string is more appropriate now? (when

that change is made, it works--well, I tested

name.string and that worked)

Presumably, _nametowidget() should be modified to work properly with a "cmdName object", rather than modifying each site that gets a widget path from a tk command.

Presumably the same problem exists with tk_focusPrev.
