updated patch

I realized first patch was using input.attrs.autocomplete.. which is not what we want, of course. Considered if it should be shared-form.attrs.autocomplete, and changing input attribute model to reference that also, but actually the semantics of the form element autocomplete attribute are different than those for input (since the presence of autocomplete on the form element does not affect the form element itself, but instead any of its child input elements). So seems like we instead need a form.attrs.autocomplete

Checked in. Thanks.
