I made the change here, but I didn't make the changes on the other lines.  It's probably worth making that change in the other places as well, largely this change reflects the coding style guides for ChromeOS.  Happy to make the adjustments to the other lines as well, unless the separation was intended by the original author, and that I'm not sure of.
