> when I use Isearch with char folding enabled, the prompt changes very

>           lazy-count-suffix-format " [%s/%s]")

Thanks for the bug report.  Some time ago I proposed the following patch:

diff --git a/lisp/isearch.el b/lisp/isearch.el
index 75a80840d6..5aa8ea2f14 100644
--- a/lisp/isearch.el
+++ b/lisp/isearch.el

   ;; If currently failing, display no ellipsis.
   (or isearch-success (setq ellipsis nil))
   (let ((m (concat (if isearch-success "" "failing ")
-		   (if isearch-adjusted "pending " "")
 		   (if (and isearch-wrapped
 			    (not isearch-wrap-function)
 			    (if isearch-forward

But it was unclear whether it's really justified to remove the message
"pending" completely.
