Take the iss53 branch in ProGit as an example.
https://git-scm.com/book/zh/v...
Question:
Does the name of a branch refer to the tip of the branch where it is located?
In other words, does a branch pointer always point to the latest commit of the branch where it is located?
If the branch name really does not need to be at the end of the branch, then how to reference the latest commit of the branch?
