Well, I don't really care how you fix it. But my point was that everyone 
was used the old vercmp behavior, and no one reported any bugs or 
unexpected behavior that would justify to change this code. For example, 
I am not aware of anyone reporting the above cases.
So I just went for the "If it's not broken, don't fix it" way.

Now if you think the new code is better and also offer a better 
behavior, that's fine.
