What did you expect to happen? (Expected behavior)

Have the full output per the format specifier

What happened instead? (Actual behavior)

fatal: bad ls-files format: %(objecttype)

What's different between what you expected and what actually happened?

%(objecttype) is not supported. It is supported in git ls-tree. For sake of consistency it would be good to have it here.
