Why is this needed?

[Steven Holte, 2017/02/17 20:21:32]

Mostly I just felt it kept prefs organized.  I'll revert it for now, since it is
causing the CL to spill out of the component.

[Alexei Svitkine (slow), 2017/02/17 20:33:44]

Sorry, I meant the include shouldn't be needed since I think this .cc file
doesn't reference the prefs in that header.

I'm not against splitting them. But I'm also OK if you want to revert it for now
like you did in the latest patch set.
