Bring forward the IndexOptions IgnoreCase option to mod_autoindex
  from Apache 1.3 for both 2.0 and 2.1 (since the patch/feature was
  previously accepted for 1.3, I'm committing without the usual vote
  specific to 2.0.)  Only small modification of David's patch to avoid
  future reformatting of the options list and better handle the strnatcmp
  side effects.
