Working as specified as in the original version. See core-tutorial and look for "git-diff-tree -p HEAD".

Well spotted.  The minimum reproduction recipe is:

     $ git diff-tree --find-copies-harder 2ad9331

Depends on how you ask.

git diff-tree --abbrev --pretty -m -M -r --diff-filter=R 0a8f4f00

or

git diff-tree --abbrev --pretty -c -M -r 0a8f4f00
