Re: GNU Parallel Bug Reports --recend='\0' isn't interpreted as NULL character.

[Andreas Bernauer]

--regexp helps a bit, but makes things slower

echo -ne "x\0y" | parallel --regexp --recstart '' --recend '\0' -k -N1
--pipe  cat -v \; echo
x^@
y

I'm not sure if this is what you intended, though.
