style: groups the overrides together:

// views::DialogDelegateView:
foo Foo() override;
bar Bar() override;

[Kevin Bailey, 2016/11/15 20:33:55]

I separated them to indicate that they all came from different
places (my fault for not specifying where.) I don't see how
(in this case) saying that the overrides come from the one and
only base class informs the reader of anything. This way rather
hides their origin.

Oh, I didn't the realize the DialogDelegateView hierachy is so complicated. You
can certainly separate it out again, but add comments to label what's overriding
what.
