This doesn't actually add any strings--it just pretty-prints them--but I'm not
sure how else to find a CL to merge, and these files have caused merge problems
in the past due to the lack of whitespace.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.

Note that this has nothing to do with OWNERS files.
