This change doesn't seem to match anything in the new mock or anything that I
requested.  He changed the spacing between the outer edge of the chip and the
menu button, but not the spacing between the inside of the edge and the trailing
end of the label.

Yeah. This is something Alan and I were discussing on IM. I expect these to all
mutate a bit -- hopefully disappearing as we coalesce with the toolbar
constants.
