Sure. The combination of expand, sed, and gnused hurts my eyes

One good lesson to take home is that by ending your lines with
'|', you can tell the shell that you are not done with the
pipeline you are forming yet. This allows you to lose all these
ugly backslashes, like this:
xyzzy |
frotz |
nitfol
instead of
xyzzy \
| frotz \
| nitfol
