Hi,

While reading the current `git repo info` implementation, I noticed that `layout.bare` is still implemented via `is_bare_repository()` in `builtin/repo.c`.

At first I thought this might be a small repository-awareness cleanup, since the `repo info` field callbacks already receive a `struct repository *`. But after tracing it further, it seems the current `is_bare_repository()` semantics are not equivalent to simply checking whether `repo_get_work_tree(repo)` is NULL.

So before trying to patch this, I wanted to confirm the intended direction:

- Should `repo info`'s `layout.bare` continue to follow the current
  `is_bare_repository()` semantics?
- Or, if `git repo info` is meant to become more explicitly
  repository-aware over time, would it make sense to introduce something
  like a `repo_is_bare(repo)` helper and use that instead?

I am asking mainly to avoid sending a misleading cleanup patch for what may actually be a semantics question.

Thanks, Jialong
