On carrying out the following steps

```
mkdir /dev/shm/test-foo -pv
for i in $(seq 1 40); do ln -sv /foo/$i /dev/shm/test-foo; done

(dired "/dev/shm/test-foo")
(wdired-change-to-wdired-mode)
(replace-regexp "foo" "bar")
```

It is seen that only the files in the visible portion of the buffer
are affeceted by the replace-regexp. The attached patch implements the
suggestion in
https://lists.gnu.org/archive/html/emacs-devel/2024-09/msg00079.html
and appears to fix the problem.

(However there still seems to be a boostrap related problem with
"Match data clobbered by buffer modification hooks" when wdired is
first loaded)
