On "jj checkout", description of the working-copy commit is empty, and the working-copy parent provides more information. It might be a bit verbose to print parent summary on every history rewriting, but I think that's okay.

Failed to export some branches:

main/sub

Hint: Git doesn't allow a branch name that looks like a parent directory of
|
|
another (e.g. `foo` and `foo/bar`). Try to rename the branches that failed to
|
|
export or their "parent" branches.
