Thanks for the patch.  The functionality is good, but the approach is
flawed.  y-or-n-p should not treat the scrolling command keys specially;
they should be part of query-replace-map just like the other responses,
similar to how the existing `recenter' response is treated.

So instead I committed a different patch, which adds window scroll via
new bindings in query-replace-map.  It provides other-window scrolling
too.
