File chromecast/browser/url_request_context_factory.cc (right):

https://codereview.chromium.org/961993006/diff/1/chromecast/browser/url_reque...
chromecast/browser/url_request_context_factory.cc:368: protocol_handlers,
request_interceptors.Pass());
nit: I would probably move request_interceptors.Pass() to a separate line (as
before) so that it's clearer that InitializeMainContextDependencies() takes
three arguments. (And it would also minimize the diff.)
