bug#60285: xref-query-replace-in-results could show an arrow pointing to the current item being replaced

[Daniel Martín]

Severity: wishlist

When you use xref-query-replace-in-results to replace some references,
it'd be great if the xref buffer showed an overlay arrow (see
xref--set-arrow) pointing to the reference being edited.  That'd give
better context about the reference that is being edited and the global
progress of the query replace operation.
