pub fn show_stat(workdir: &Path, sha: &str) -> Result<Vec<ChangedFile>, String>Expand description
Files changed by a commit: path | +N -M rows for the dive view.
Paths come from numstat’s NUL-delimited machine form, so native —
never C-quoted, possibly non-UTF8 — names arrive as the worktree
identities commit_file_diff expects.
