You need to find all the commits that are child of X in the first place.
What should happen if your colleague has such a commit in his repository
(which you haven't fetched from yet), you enumerated all children of X
known to you in your graft file and then you fetch from him?  You need to
enumerate all children of X again to keep the graft file up to date.
  

Ok, that is enlightening. When trying to sort out the differences, 
advantages and disadvantages of
operating on arcs (grafts like) or on nodes (replacements like) I was 
thinking local, rather than
distributed. Now the advantage of working on nodes is much clearer to me.

Thanks as usual for the very clear explanation.
