Several Debathena packages use a transform script that's something like perl -0pe 's/^foo$/bar/m or die' to get the effect of sed s/^foo$/bar/ but cause a build-time error if the regex doesn't match anything. We should document this and why it works.
See for instance https://github.com/mit-athena/ssh-client-config/blob/master/debian/transform_ssh_config.debathena
