The command line is this:

    $ lout -r6 infile > outfile

the -r6 says run 6 times. On the 5th run, prg2lout (the program lout
runs) exits with status 1 (and it shouldn't). Annoyingly if I run
prg2lout standalone it works okay, and if I do -r4 and then -r2
everything works fine.

Now I'm really giving up on it!
