I initially thought two hooks might be useful because that allows to
put into hooks something more than planned switching buffers or Info nodes.
But perhaps one hook and one variable which enables wrapping immediately
after failing is enough.

Yes, `isearch-wrap-hook' is a better name, even for a combined hook.

Perhaps the plural form `isearch-wrap-functions' is better when using
`run-hook-with-args-until-success', as Richard suggested, to try
multiple functions until one of them returns a non-nil value.

I think `isearch-wrapped' should be set to t even when the
user-function is run. As I can see from isearch.el, the variable
`isearch-wrapped' is used only to display the proper message
(either "wrapped" or "overwrapped"). I already added the condition
in the previous patch I sent that if `isearch-wrapped-hook' is defined,
to not display the prefix "over" since this makes no sense for cases
with switching buffers. But the message "wrapped" still seems
appropriate to indicate that the search was moved into another buffer
or Info node.
