IteratorOfCartesianProduct and empty lists

[isadofschi]

IteratorOfCartesianProduct gives the following error if one of the arguments is empty:

	Error, Each arguments must be a finite collection called from
	IteratorOfCartesianProduct2( arg ...

I think this is a bug. For example:

	IteratorOfCartesianProduct([1,2],[]);

gives this error, while

	Cartesian([1,2],[]);

correctly returns [].
Calling

	IteratorOfCartesianProduct([[1,2],[]]);

also gives an error.

I have tried this in GAP 4.8.4 and GAP 4.8.10.

This is already fixed in the master branch and in GAP 4.9, due to be released RSN

Ahh, actually I mixed up two different bugs here: the one you report is NOT fixed in GAP 4.9 nor in the master branch! Sorry for the confusion.
