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.

先檢查 Branch.Commit()、repository.Commits()、ICommitLog 和 IQueryableCommitLog，以了解現有的查詢 API 以及 CommitFilter 的套用方式。檢查相關測試，然後將完成標準定義為支援經過篩選的 commit 查詢，包括從 origin/master 之類的任意 branch 取得 first-parent 歷史，而不只是從目前的工作 branch 取得。
