Hi,

While testing Tkinter.Text I've found some problems and it would be good
to fix them in trunk.

The methods edit_redo, edit_reset, edit_separator and edit_undo doesn't
return anything, so I would suggest to remove the return statements there.
The debug method doesn't return a boolean when we set a value for the
debug option, so the getboolean function fails:

>>> import Tkinter
>>> text = Tkinter.Text()
>>> text.debug()
False
>>> text.debug(1)
...
_tkinter.TclError: expected boolean value but got ""


I'm also suggesting a change in the bbox signature. Right now it
supports receiving multiple args, but the bbox command in Tcl expects a
single item as the index. I believe it makes more sense to indicate that
it accepts a single argument. An index like '1.0 +1c' needs to either be
passed as '1.0 +1c' or ('1.0', '+1c') (a tuple holding the two parts),
not as '1.0', '+1c' (two arguments).

The suggested changes are mostly trivial, but there should be comments on the change to the bbox signature.
