I am playing around with some make options that I *would* want
to pass through crunchgen (if I can get them to work right).  By
having only the change in the rescue/Makefile, it would be easy
to get that to happen when I want it to.  I don't feel too
strongly about it, but this just "feels" more flexible.

It would probably be a good idea to put a short paragraph in
the 'CAVEATS' section of the man page.  Someday maybe we could
change crunchgen so it knew what output lines it could ignore,
but there's no need to worry about that right now.
