I already have my brain wired that "\0 terminators in Git are -z".
Thus I'd assume "git grep -z  .. | xargs -0" would work.  Today it
doesn't without this patch, but if the patch was added I'd assume
it would work.

Perhaps I'm too close to git as a contributor and experienced user
to realize any brain damage.

I'd rather stick to "-z" in Git.  At least its consistent.

Its not like tools outside of Git are all that consistent.  GNU
grep uses --null/-Z.  xargs and perl use -0.  find uses -print0.
The human at the keyboard already has to navigate this rats nest
between different tools, but within a tool (git) we should be as
consistent as we can.
