Hi,

Suppose I have "git format-patch" two commit from a repository like
following:

  git format-patch -1 cf1c9ccba730
  git format-patch -1 d1a2930d8a99

Now, how to determine the commit order of these two patch in repository?
```

Do you mean something like:

$ git merge-base --is-ancestor cf1c9ccba730 d1a2930d8a99

and:

$ git merge-base --is-ancestor d1a2930d8a99 cf1c9ccba730

?

```
