newline before }, update comment.

Done. It was removed by 'cl format'.

If git cl format removes the whitespace, then perhaps to make it consistent, we
should instead have removed the newline after 

"namespace features {"?

Just checked other files in this directory, and it seems to be bug of cl-format
and
we should have newline before&after namespace.
