PATCH: muddled completion search status

[Oliver Kiddle <okiddle@yahoo.co.uk>]

If a completion match search is active, then cursors/tab etc are used to
select a different match and then searching is restarted, the old status
(wrapped/failed etc) is included in the status line despite the search
string being empty.

There's a further feature where if you press Ctrl-S (or whatever) again,
it will restore the last search string used. This feature is also
triggered if your next key is that for a reverse search. I found this to
be confusing. The following will only restore that last search if you do
the search twice in the same direction.
