[Rd] stack imbalance in contour

[Patrick Burns]

I'm not sure if this has much significance or not -- but
it sounds rather ominous.  It doesn't appear to be new
as it happens with 2.0.0 in Linux (but the formatting of
the warning messages has improved).

 > contour(array(3e10, c(10,10), list(1:10, 11:20)))
Warning: stack imbalance in 'contour', 20 then 24
Warning: stack imbalance in '.Internal', 19 then 23
