You haven't gotten the new commits from origin, so your local repo can't 
know how ahead/behind it is from its remote version.

Run `git fetch origin`.

Now if you run `git status`, it should show you that you are X commits 
behind origin.

`git pull` does two things: `git fetch` and `git merge`. fetch 
"downloads" all the commits from remote, and merge then puts them in 
your local branch. So if you do a `git pull`, developer A's changes are 
now merged into your tree. But if you only do a fetch, origin/master 
gets updated, but not your local master. So now status can know how far 
you are behind, but your local branch is not changed yet.

Once you are ready to finally get those changes in your local branch, 
run `git merge origin/master`.
