a git rebase demo from Pro Git

git_rebase_demo.md

Now $git show-branch master server client shows like this:

<-- commit0 <-- commit1 <-- commit2                 master
                  \
                   \-- commit3 <-- commit4          server
                          \
                           \-- commit5 <-- commit6  client

What does $ git rebase --onto master server client do?

1. Checkout client branch
2. Figure out the patches from the common ancestor of server and client (commits of git log server..client)
3. Replay the patches onto master

Run $git show-branch master server client again:

                            master                  client
                               |                       |
<-- commit0 <-- commit1 <-- commit2 <-- commit5 <-- commit6
                  \
                   \-- commit3 <-- commit4
                                      |
                                    server
