Please clang-format the cl

(the presubmit should have warned about formatting, but it won't actually
prevent you from uploading it/committing it)

Good catch. My presubmit did not raise any warnings about this and it turns out
git cl format was throwing a permission exception which was silently hidden
during presubmit checks.
