1) Are there any option to move the cursor to the start of the candidate

seems a bit hacky.

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.

Ok for me.

2) I want to disable wrapping and I see that there is an
`isearch-wrap-function` but it is a variable not a custom and it is not
documented in detail what is expected to be there.

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

Sorry I don't get this one, on yesterday you gave what was IMO the best
proposal. Provide 3 options for: disable wrapping, pause and just
wrap. Are these really so hard to provide?

* Any way if there is a reason for this; then I won't argue about that.

3) In general many of the customizable variables in isearch are defined
with defvar so it is difficult to distinguish between internal and user
exposed ones. Just to mention some examples:
isearch-push-state-function, isearch-filter-predicate, the hooks,

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

I use some of them as simple hooks. But again (go to *)
