vi: searches in colon commands should wrap
The '/' and '?' search commands wrap to the other end of the buffer
if the search target isn't found. When searches are used to specify
addresses in colon commands they should do the same.
(In traditional vi and vim this behaviour is controlled by the
'wrapscan' option. BusyBox vi doesn't have this option and always
uses the default behaviour.)
