Tiny nit: we also tend to terminate the last enum value with a comma.
The reason here is that it makes it easier to add new values going
forward while only having to change one line.

This error message isn't true anymore, as we also support
"--format=lines" now.

You also have to adapt `cmd_repo_structure()` to handle this new vaule.
Otherwise it would `BUG()`. I guess the most reasonable change here
would be to treat "lines" and "keyvalue" as equivalent?

Thanks!
