To ask about how to get grep to emit nuls?  I don't think so.
(Though if the OP had thought through his question and realized
it boiled down to that, perhaps he would have just consulted
the grep manpage looking for such an option.)

xargs -d '\n' would be preferable to doing a separate newline
translation step.  I was going to add the qualifier "unless you
need non-GNU xargs compatibility", but I see that POSIX xargs
doesn't even have -0 (!), so that may be something of a lost cause.
