    git: load new files not found in git index
    
             ** This requires an local patch to libgit2-glib **
    
    This will load files in the working directory that are not yet staged,
    and would otherwise not show up in the git index.
    
    I'm not sure how we are going to deal with this long term, but figured
    this is a good place to start.
