This doesn't feel like the right place for this code. From your description the
setting applies only to browsers, right? Some where closer to browser is a
better place.

I'll try it out in browser_commands.h . (I originally had it in an anonymous
namespace in browser.cc, but I think longer-term it shouldn't just be
browser.cc's call, so moved it out so other things can use it it.)

Done.
