Only one string16(), I believe?

[James Hawkins, 2011/07/26 23:18:26]

Indeed, I was looking at the wrong string.  Done.

[Peter Kasting, 2011/07/26 23:10:52]

Nit: No else after return.

Doing this with a conditional like you have it is OK, just DCHECK the button
type instead of "handling" failure, i.e.:

  if (button == BUTTON_OK)
    return ...;
  DCHECK(button == BUTTON_CANCEL);
  return ...;

[James Hawkins, 2011/07/26 23:18:26]

Done.
