Why is your impression that the null character is "dirty"?

E.g. that's how find|xargs etc. usually work.

Another alternative would be if you gaurantee that your varn's don't
have commas then put the path last.  But that doesn't account for
filenames containing newlines.

Another alternative would be to wrap with some kind of serialization
library. But really, what's so dirty about null?
