Which class comments?

[kelvinp, 2014/11/01 00:42:00]

The comments in Widget.h

+  views::Widget* widget =
+      CreateDialogWidget(this, /* delegate */
+                         nullptr /* parent window*/, nullptr /* parent view */);

[Wez, 2014/10/31 21:22:24]

put these one-per-line so that the comments are more readable.

[kelvinp, 2014/11/01 00:42:00]

Done.
