As mentioned in my comments about the 'diff-index' replacement, this
'\n' should probably be '\0', and we should keep the '-z' flag in 'git
update-index', in case somebody has a '\n' in their filenames.

While creating such a file is probably not a good idea anyway, we
should still be able to handle it (and have been before this, so we
shouldn't break it).
