It's worth mentioning that the ed these scripts were written for didn't have the buffer-modified warning at all --- the scripts are full of fragments like this:
ed - $em_table <<'A' > X 1,/^$/g/ /s// /gp A (from https://github.com/davidgiven/ack/blob/4d24666432a4a01a67ed9b993c912f44b4cfe0a8/modules/src/em_data/new_table, written in 1985.) I believe this worked fine on 1.10.
