pygit2.RemoteCallbacks.push_update_reference doesn't get full error message

When a push fails on a pre-receive hook, which sends a error message as to why the push failed validation, the message from pygit2.RemoteCallbacks.push_update_reference is only pre-receive hook declined. Is there any way to get the full output from the failed push?

Also, if I raise an Exception on push_update_reference, it's caught somewhere else and re-raised as "GitError: git_push_status_foreach callback returned -7", so, I can't properly raise any kind of exception to clean up anything, or, output any custom error to the user. What would be the proper way, am I missing something here?

首先跟踪 pygit2.RemoteCallbacks.push_update_reference，以及失败的 push 状态和 callback 异常是如何传播的。确定是否可以公开完整的 pre-receive hook 输出，以及 callback 失败是否可以支持清理或自定义的面向用户的错误；两种情况的行为都得到覆盖即表示完成。
