I agree that it's better to bind C-h to isearch-mode-help by default.

But is it possible to unbind it in .emacs for those users who want
to get the top-level help with C-h?  In older versions of isearch.el
there was such a comment:

      ;; You can reenable global keys by binding them locally to nil.
      ;; For the help char this doesnt work quite as expected because
      ;; isearch-mode is not a major mode.  Also the echo area is not
      ;; restored after the help command while isearch-mode is
      ;; still active.  Furthermore, we should not assume that the
      ;; help-command is on C-h.  But here is how it would be done:
      ;; (define-key map "\C-h" nil)

Perhaps this comment should be restored in isearch.el after uncommenting
the line with C-h binding.

And then what about [f1] and [help] keys?
