Hi Stephane, 

Cancelling is very tricky to get right, and I'm glad for your attention to
it in ct-lib, because we currently lack an expert.  But I'm afraid neither
your reasoning nor your remedy is quite clear to me yet.  :-(

Could you post the output of "diff -u" so I can see exactly what you mean
by "the final line", and explain again how the logic goes awry?  I would
be much obliged.
