No you are right, thats the only spot at the moment. 
What i meant however was the design-intent/enviromental-rules for all
actions that branch is to clone, and when you do that you reset those
fields i described. I am looking at the new clone and i can see
Herbert's point - it does look less pleasant to stare at with that
#ifdef; i will send a patch to pull it out and also write a small doc to
describe the environmental rules.

cheers,
jamal
