Re-using the Submit() method causes a small problem that the method (in
searchbox.cc) will now overwrite searchbox.value with the query. If you don't
want to invent a new IPC (and I'm in favour of not adding new IPCs), you need to
special-case the empty query there.

Ok, I prevented overwriting of the query_ field in Searchbox::OnSubmit when
called with an empty query string.

Remove this. We shouldn't need to send any such info to the overlay.

[robertshield, 2013/04/01 18:14:49]

Done.
