title: Git is ignoring files that aren't in gitignore
body: <p>I have a git repository that is ignoring image files as well as a few other files, but my <code>.gitignore</code> file only has it ignoring a <code>config.php</code> file.  Is there some global ignore file somewhere that I can't seem to find?  I have to specify files to add them now, and it's giving me this warning:</p>
  
  <blockquote>
    <p>The following paths are ignored by one of your .gitignore files.</p>
  </blockquote>
  
  <p>The contents of my <code>~/.gitconfig</code> file are only my e-mail address.</p>
