Yeah, same:

    dd if=/dev/zero of=file count=1
    echo 'file diff=debug' >.gitattributes
    git config diff.debug.textconv 'echo >&2 "got $*"; xxd'

shows (with "git add --intent-to-add file; git diff file") the xxd dump of zeros from the working tree. Then

    git commit file -mwip
    dd if=/dev/zero of=file count=2
    git diff file

shows a diff between a temp file and the working tree (but still correctly showing the new block of zeros).
