Sed has the ability to pull into the current line the next line, appended and
separated by a "\n" character. It's hard to use correctly, I've found, and my
simple demo:
sed -e '/^$/{N;N;N; s/^\n\n\n$/===4 blank lines==/; }'
Does not quite work as I'd hoped. But hopefully it's enough to get you started.
