Makes sense to me.  This has also the advantage to cause a crash if
there is an attempt to refer to those empty arrays in case of future
refactoring, which is rather defensive.  By looking at
findObjectByOid(), I can also see that we check for a negative number,
so I concur with Ranier's comment to check after that on top of 0.
If there are no objections, I'll apply that on HEAD.
