The line at zero is how I would have done it on previous versions of rrd.
It's not totally clear from the manual but I interpreted the idea of
changing STACK to an argument of AREA was so that you wouldn't have to make
a special case for the first item in a stack.
If the behaviour is not supposed tobe be this way segfaulting rather that
giving some kind of error message can't be good.
