bug#11746: feature request: `isearch-query-replace' should open invisible text

A quick try does exactly what is needed:

                                          (< (1+ (point)) limit)))

But it would be better to implement this the same way as for isearch
filters.  Adding the same filters in replacements also will make the
variable `query-replace-skip-read-only' obsolete.
