Calling BatchHttpRequest.add() as shown in examples generates warning output on console. positional decorator incorrect?

[GoogleCodeExporter]

What steps will reproduce the problem?

Use batched HTTP Requests as shown in this example code:

  batch = BatchHttpRequest()
  batch.add(service.animals().list(), list_animals)
  batch.add(service.farmers().list(), list_farmers)
  batch.execute(http=http)

Ref: https://developers.google.com/api-client-library/python/guide/batch

What is the expected output? What do you see instead?

No output expected; rather, I see this on the console:

  oauth2client/util.py/util.py:117:positional_wrapper(): add() takes at most 2 positional arguments (3 given)

What version of the product are you using? On what operating system?
  google-api-python-client==1.0

Please provide any additional information below.

The batch operations succeed, so it appears that there's something wrong with 
the declaration of BatchHttpRequest.add().

If you invoke .add() with 'callback=' keyword argument, the message does not 
appear.

  batch.add(service.farmers().list(), callback=list_farmers)
