Thanks Yonik. I wasn't asking about the specific details, but of the
consequence. I seem to remember (incorrectly , or v1.2 only maybe) , that if
one wanted assurances that the case above happened in the right order, one had
to commit after the deletes, and once more after the adds.
This not being the case, I am happy :)
Thanks again,
