As you see from the discussion, adding a defcustom makes little sense,
because this feature might be needed only occasionally, so better
to be bound to a special key, e.g. C-RET to exit and move to other-end,
S-RET to exit and mark the found string as a region.

isearch-wrap-function can't be a defcustom too, because it's impossible
to implement automatic wrapping by a wrap function.

Most of these functions are intended to be modified by different modes
using add-function, so again there is nothing to customize here, sorry.
