Options arg not really optional?

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Pass a two arg call to $.csv.toObjects(csvData, callback)
2.
3.

What is the expected output? What do you see instead?
Callback is is not invoked. If an empty object is passed as second arg:

$.csv.toObjects(csvData, {}, callback)

then the callback is invoked.

What version of the product are you using? On what operating system?
0.71

Please provide any additional information below.
Maybe its just my understanding of optional args .... if both "optional" args 
need to be present, maybe the docs need amending?
