LGTM. I did this locally and never got around to committing it.

Thanks.  Just realized I need to get myself added to the AUTHORS file and add my
attribution to the commit message.  After I do that, would you mind committing
this for me?

OK, I've added an attribution line to the commit message, and I've submitted
https://codereview.chromium.org/11092082/ adding myself to the AUTHORS file for
this first-time contribution.

Would someone mind reviewing and merging
https://codereview.chromium.org/11092082/ followed by this commit?

Thanks,
Josh Triplett
