"""`git diff` across all repos in a top workspace.

    git-diff [GIT_DIFF_ARGS...]

Runs `git diff` in the workspace root (top / <feature>) and in each
manifest repo subdir (ksgpu, pirate, ...), under a per-repo header. Extra args
are passed through to git, e.g. `git-diff --stat` or `git-diff --cached`.

Exits with the worst git exit code across the repos (note: a plain `git diff`
returns 0 even when there are changes; use `--exit-code` if you want non-zero).
