`git diff --break-rewrites` does not work (otherwise it should break rewrite into delete and create, for `--find-renames` to work)

Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

cd '/'; cd '/'; rm --force --recursive -- './test_git2'; mkdir "$_"; cd "$_"; mkdir --parents -- './repo'; git init './repo' echo -e 'a\nb\nc\nd\ne\nf\ng\nh\ni\nj' >'./repo/file1' echo -e '0\n1\n2\n3\n4\n5\n6\n7\n8\n9' >'./repo/file2' git -C './repo' add './file1' './file2' mv './repo/file2' './repo/file3' mv './repo/file1' './repo/file2' git -C './repo' add --intent-to-add './file3' git -C './repo' diff --break-rewrites='50%/50%' --find-renames='50%'

What did you expect to happen? (Expected behavior)

`git diff` outputs: file1 rename to file2, file2 rename to file3

What happened instead? (Actual behavior)

`git diff` outputs: file1 remove all content, file2 complete rewrite, file3 add all content

What's different between what you expected and what actually happened?
