Mr. Trawick was dead on, and this revealed a much bigger bug.
  Factor out the opts/override merging (since we do it three times)
  and eliminate all the nasty goto's.  This bug likely caused all
  sorts of dir_walk configuration issues including htaccess issues.
  Also add a few more docs where things aren't so obvious.
