I wanted to do it that way, but it seemed less intrusive this way.

I agree that it is the correct thing to do, though.

Good point.

I found another nitpick: file removal doesn't seem to generate a good 
diff in "git-diff-tree --cc" (but it's correct in the new "raw" format 
diff).

Here's a test-case, in case you care. Do "git-diff-tree --cc HEAD" in the 
merge-test directory.

Finally, I think it would be good to have a "--ignore-mode" flag that 
drops the mode info from the raw format (that repeating "100644" really 
isn't very interesting, and caring about mode changes is pretty rare).
