title: Why won't Xcode commit some artifacts as part of folder context commit?
body: <p>In Xcode, I created a new project and in the wizard opted to create a git repo.  When the wizard finished, all the artifacts were committed to git.</p>
  
  <p>As I've been editing, whenever I right-click on the top/first yellow folder in the Project Navigator and choose 'Source Control > Commit Selected Files', some file types (.storyboard, main.m, .xcdatamodeld) cannot be committed from the commit window that displays.</p>
  
  <p>The Project Manager displays the 'M' icon to the right of all these files, so it knows they are modified.  Furthermore, if I right-click on the individual file and do the commit, it allows me to commit.</p>
  
  <p>I'm using Xcode v4.5.2.</p>
  
  <p>Two questions:</p>
  
  <ol>
  <li><p>Why does it list the '.storyboard' in the commit window, but will not let me select it for commit?</p></li>
  <li><p>Why do the other files (main.m, .xcdatamodeld) not even display in the commit window?</p></li>
  </ol>
