[whatwg] [wf2] Filtering datalist with pattern

The WF2 spec does not say anything about filtering autocomplete lists
on pattern and Opera 9 does not do it. However, autocomplete entries
that would fail form validation are not particularly useful.
I suggest saying that potential autocomplete items (whether supplied
by the UA itself or read from a datalist) should be tested against
the datatype and the pattern of the form field being filled and
should only be shown if they match both the datatype and the pattern.
(Real-world case: The autocompelete menu for the document field at
http://hsivonen.iki.fi/validator/
shows ftp and file URLs in Opera 9 even though the pattern only
matches http and https URLs.)
