You couldn't reasonably do a "git-whatchanged -p" Yes, I understood and agreed to that logic on May 27th. That's why the message you are responding said we could add a new flag, to give the choice to the user to accept full-tree scan. The "diff-tree --stdin that follows rename history" example might want to have some change in either the core side of diff, or in the rev-list. It may help to have both. I still haven't thought through the issues. BTW, I really liked your example that piped multiple diff-trees together. That is a neat trick.
