I have to agree with Tian's comment on v2, this part here looks wrong. I
don't think we should depend on `startup_info` here, but we should
exclusively rely on whether or not the caller has passed in a
repository. And that will likely require a bit more scrutiny to figure
out whether there are any callers that shouldn't pass in a repository
because it's not initialized.

Alternatively, we could go with Tian's suggestion of checking for `repo
&& repo->gitdir`.
