I'm sure later someone might want to add more args such as e.g.
text-property-search-forward has PROPERTY &optional VALUE PREDICATE ...
So better to change the signature in anticipation of adding more
args after PROPERTY:

  diff --git a/lisp/isearch.el b/lisp/isearch.el
  -(defun isearch-search-fun-in-text-property (property &optional search-fun)
  +(defun isearch-search-fun-in-text-property (search-fun property)

  diff --git a/lisp/dired-aux.el b/lisp/dired-aux.el
