It seems this `+' comes from the diff indicator from the
beginning of the diff line from failed patching.

So I attached a whole new file isearch-repeat.3.el
for your convenience.

But please note that it contains a new implementation
because I found problems in the previous implementation:
when COUNT is added to low-level isearch functions then
they don't skip filtered-out matches.

So a better place is in isearch-search after
`funcall isearch-filter-predicate'.  But the problem
is that when (= (match-beginning 0) (match-end 0))
then it doesn't move point one character forward like
isearch-repeat does.  So the right place to use COUNT is in
isearch-repeat.

Please try a new implementation:

[isearch-repeat.3.el (application/emacs-lisp, attachment)]
