Fair enough.  I've revealed my antediluvian origins :)   All the same,
while I would never opt for expressing the spam score in the exit code,
I do think 0/1/2 (or whatever number prevents Matthias's onions from
getting in a bunch) for spam/nonspam/unsure is a useful modification. 
I made it for myself several months ago and would be glad to see the
convenience made available to the general bogofilter user population.
