CommitFilter for Branch.Commits

My use case is that in a give repository, I am on branch X . There is a remote tracking branch origin/master.
Note : X is not tracking origin/master.

Now i want to do something like git log origin/master --first-parent. Today the only way to use CommitFilter is on repository.Commits() which will perform the operation on current working branch i.e. X. It would be good if Branch class's Commit() method return IQueryableCommitLog instead of ICommitLog.

首先检查 Branch.Commit()、repository.Commits()、ICommitLog 和 IQueryableCommitLog，以了解现有的查询 API 以及 CommitFilter 的应用方式。检查相关测试，然后将完成标准定义为支持经过过滤的 commit 查询，包括从 origin/master 之类的任意 branch 获取 first-parent 历史，而不只是从当前工作 branch 获取。
