-u  Treat unset variables as an error when substituting.

I think the behaviour is consistent with the documentation.

The question is rather when to consider a variable set or unset.

I'm not sure about the intended meaning here, but I don't consiter $@ as a variable (but a special parameter).

Though regarding what Chet said to this topic before, maybe the documentation should be rephrased.
