如果我只想克隆一个分支，我该怎么做？
git clone url是git clone url --all是什么意思？
[hugemeow@home base]$ git branch
* master
[hugemeow@home base]$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/donut-release
remotes/origin/donut-release2
remotes/origin/eclair-passion-release

事实上，我的问题与Clone only one branch不同，尽管答案可能有点类似......
顺便说一句，如果该链接是解决方案，在从远程仓库克隆之前，如何获取分支列表？ （该链接中未提及此问题，如果该链接可以回答我的问题，则应该预先解决此问题。）
