Porcelain layers often want to find only names of changed files,
and even with diff-raw output format they end up having to pick
out only the filename. Support --name-only (and --name-only-z
for xargs -0 and cpio -0 users that want to treat filenames with
embedded newlines sanely) flag to help them.
