title: I change the capitalization of a directory and Git doesn't seem to pick up on it
body: <p>I'm developing a project on OS X Lion that is under Git version control. I had these lowercase directories and then later capitalized them (e.g. emailaddresses => EmailAddresses), but Git doesn't seem to recognize the change. It still thinks the directories are lowercase when I run <code>git ls-files</code> and other commands.</p>
  
  <p>Is this harmless, or should I do something else to get Git to pick up on this change?</p>
