Yeah, I think the problem is that the diffcore chain doesn't know enough
about the merge. It just sees the filepairs between the commit and each
parent separately. I looked into this recently as part of this thread:
http://article.gmane.org/gmane.comp.version-control.git/165743
I described some reasonable semantics there, but implementing them
looked non-trivial. I'd be very happy to be proven wrong. Patches
welcome. :)
