Hmm - but we could also try to do this when query-replace is invoked.
Similar to what we do when invoking isearch.

Do we handle wdired differently only because of this problem?

|  ;; Original dired hook removes dired-isearch-search-filenames that

|  (remove-hook 'isearch-mode-hook #'dired-isearch-filenames-setup t)

Maybe we could solve this in some other way?  Then, isearch and
query-replace would just look whether filename only matching is enabled
or not, and do the according setup when any of them is called by the
user.


Michael.
