Fixing problem with case insitive file systems.

Would you believe that I wrote all of this on a Mac? I just happen to be not using HFS for the partition I did this work on. Oops :)

  Fix silly little problem with case insensitive filesystems.
  
  Funny thing is that I wrote all this on a Mac, but I don't use HFS on that partition so I never noticed that it would be an issue.
  
  Oops :)
