SearchTermsData::InstantExtendedEnabledParam() checks to see if instant-extended
is enabled (as opposed to just query-extraction being enabled). I was under the
impression that only the latter is enabled for android. Is that not true?

When you try this, do you actually get a non-blank string? (specifically,
"espv=2")?

https://codereview.chromium.org/12319124/ is in-flight and will cause
InstantExtendedEnabledParam() to return a non-blank string.

Oh, right. Sorry I forgot about that CL.
