Add "git branch" script You can use it as git branch <branchname> [start-point] and it creates a new branch of name <branchname>. If a starting point is specified, that will be where the branch is created, otherwise it will be created at the current HEAD. The sequence git branch xyz abc git checkout xyz can also be written as git checkout -b xyz abc as per the previous commit. 20 years ago			`#!/bin/sh`

[PATCH] git-branch: avoid getting confused by empty or nonexisting branches. When not specifying the start point explicitly, we ended up emitting ^0 in addition to the default HEAD. Be careful to see if we have "$2" before finding out which commit to base the new branch on.
