nit: Remove this line, keyword is already taken care of above.

Done.

+  data.SetURL(TemplateURLRef::DisplayURLToURLRef(UTF8ToUTF16(url.spec())));

[gab, 2013/06/28 00:28:45]

What's the difference between taking
TemplateURLRef::DisplayURLToURLRef(UTF8ToUTF16(url.spec()) versus url.spec() (IE
and FF didn't do the same thing here and it's not clear to me why... was one
impl simply incorrect?)

[ananta, 2013/06/28 01:03:29]

The DisplayURLToURLRef function does some processing like replacing %s in the
url with {searchTerms}, etc. This works correctly for both IE and FF

I see thanks. re-lgtm.
