Describe the bug:
On page https://git-scm.com/book/en/v2/Git-Branching-Rebasing, https://git-scm.com/book/en/v2/images/interesting-rebase-1.png, I am assuming the commits are done in the order indicated by the number, e.g. C1 first then C2, C3, C4, etc. If so when C5 & C6 are created, branch server is pointing at C4. In order to get branch client to begin at C3 the user would have to use the command git checkout [C3 SHA] or similar after adding C5 & C6. If the user executes git checkout server (as I expected) the tree is wrong; client branches from C4, not C3.
Steps to reproduce:
view page https://git-scm.com/book/en/v2/Git-Branching-Rebasing, section "More Interesting Rebases"
Expected behavior:
This is not technically wrong. The client branch could have originated after a checkout of the raw C3 SHA, but if the user performs git checkout server to begin the client branch the command git rebase --onto master server client results in rebase conflicts, and it also means that "C3" is included. As a naive git user the first time I tried to follow the example I executed git checkout server not noticing that it was pointing at C4 instead of C3 before adding C8 while trying to reproduce the sequence. This led to difficulties in the rebase.
After studying the problem for a while I figured out what the issue was and performed a checkout on the raw C3 SHA before creating the client branch. This did behave as I expected, but it feels like this was not how the author intended the example to proceed.
It has just now occurred to me that immediately after creating commit C3 the user could create branch client with no commits then switch back to branch server and create commit C4. Branch client would then point at C3, and everything would work as I think is expected. To me it would be desirable to include these instructions for those of us who attempt to reproduce the flow in the diagram.
