title: git submodule init not pulling latest commit
body: <p>I have a git repo with a git submodule inside of it. The submodule is hosted on bitbucket. I want to update my local copy of the submodule to its latest commit. I tired "<strong>git submodule update</strong>" however that is not doing anything. So I tried deleting the submodule folder and then doing "<strong>git submodule init</strong>" However it simply pulls the initial submodule commit, not the latest.</p>
  
  <p>How can I get my local submodule to update to the latest commit?</p>
