Given two tagged versions "urtext" and "edited-print", another variant for
the filter function would be to implement a function

\apply #(annotated-music '("edited-print" "urtext"))

that basically filters out the edited print, but additionally creates
proper footnotes whereever the urtext differs from the edited print.
