general: braces are also optional in one-line for loops. It also looks nicer and
is consistent with our typical request to elide braces with one-line if blocks.

Thanks Xiyuan. Luis, PTAL.

File components/arc/arc_bridge_service.cc (right):

https://codereview.chromium.org/2416633002/diff/20001/components/arc/arc_brid...
components/arc/arc_bridge_service.cc:80: for (auto& observer : observer_list())
Added <LF> since line 80-81 does not fit in one line. Also, one-line for does
not seem to be very popular in Chromium.

[Luis Héctor Chávez, 2016-10-12 18:40:30]

Thanks for being proactive about this!
