Summary: Empty Array generate an error if transported via COM

Initial Comment:
The new code for arbitrary SafeArrays wont allow the
transport of empty array. To resolve this problem an
else clause has to be added to oleargs.cpp in 
PyCom_CalculatePyObjectDimension


		if (!PyBuffer_Check(obItemCheck) && 			
			PySequence_Length(obItemCheck)) {
			...
		}
		//  New Code
		else {
			// Just an empty list so increase Dimension
			lReturnDimension += 1;
		}
		//  End new Code

Can you please attach a test case that fails with the
current code?  eg, I changed testvb.py to add:

    # Empty array
    _DoTestArray(vbtest, ())
    # Empty child array
    _DoTestArray(vbtest, ((), ()))

Further, I can't find the code you reference in oleargs.cpp
- if you still believe it must be added, can you supply a
patch (or the entire file if necessary)
