+Subject: test-prune: Read to the end of cut(1) output
+
+If we use head(1) to take only the first two lines, then cut(1) and
+earlier pipeline entries are killed by SIGPIPE (if they have not already
+terminated), and that's flagged as an error under `set -o pipefail`.
+Use an equivalent sed command to take exactly the second line, but
+without SIGPIPE.
