Patch to replace tuple() with tuple([])

[<pe...@ha...>]

Hi...

Attached is a patch against 2.0.0pre07 which replaces instances of tuple()
with tuple([]). This is necessary since tuple() is not valid under
python 2.1.

For example, under python 2.1:

 >>> print tuple()
 Traceback (most recent call last):
   File "<stdin>", line 1, in ?
 TypeError: tuple() takes exactly 1 argument (0 given)
 >>> print tuple([])
 ()
 >>>

Under python 2.2:

 >>> print tuple()
 ()
 >>> print tuple([])
 ()
 >>>


Could you please apply this? I realise that you may think python 2.1 is
old/deprecated, but it seems like not much work is required to keep it
functional for a little bit longer (ideally, I'd like it to work until
the next debian release).
