为什么git会对git pull提供不同的回复？
(dev) go|c:\srv\lib\django-cms> git pull
Already up-to-date.
(dev) go|c:\srv\lib\dk> git pull
Current branch master is up to date.
这两个回购来自github，我在两个回购的主分支上：
(dev) go|c:\srv\lib\django-cms> git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean
(dev) go|c:\srv\lib\dk> git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean
