title: Handling submodules while taking pull on parent repository
body: <p>I have created one simple android application. In this application, I am using another submodule git repository. When I add git submodule into my parent project it creates some entries in the parent's git folders and creates some files.</p>
  <p>Now here I am having two active git repositories. One is the parent one and the other one is the child submodule. When I am trying to take a pull from a parent repository it throws me an error by saying non-committed local files.</p>

  <p>I don't want to commit this submodule-related file into my parent's repository.</p>
