This is due to [1: 644cdd1aa0].  'git grep' also has a '--null' option,
but the output is a bit different.  Here is a patch to handle it,
although it's not complete: it doesn't take the value of
grep-use-null-filename-separator into account.  Perhaps we should
instead disable this option by default; when I introduced it, I didn't
think about the fact that grep.el is used for not-quite-grep programs as
well.
