All mod_autoindex query parsing is now quietly quashed with the
     IndexOption IgnoreClient.  The IndexOption SuppressColumnSorting
     still drops the column sort <a href>'s for the column headers, but
     IgnoreClient is required to ignore these Query options entirely.

     Introduced new mod_autoindex query argument parsing for F=[0|1|2]
     to allow the client to select plain, FancyIndexing or HTMLTable
     formatting, V=[0|1] to inhibit or enable version sorting, and
     P=pattern to return only specific files.  The old Query Arguments
     were reorganized as C=f for sorting column 'f' (same N, D, S, or M
     as before), and O=A|D for ordering ascending or descending.

     Docs and an Example are provided in mod_autoindex.html

null terminator in the right spot for the tag_val if the value contained
backslashes.  This caused #if, #elif, and #else expressions with backslashes
to be incorrectly evaluated.

     Introduced new mod_autoindex IndexOptions flags; SuppressIcon to
     drop the icon column and SuppressRules to drop the <hr> elements.
     These are necessary for HTML 3.2 final formatting rules.

     Introduced HTMLTable to create rudimentary HTML table listings
     (implies FancyIndexing).  Necessary for alternate charsets, since
     the columns are borked by multibyte characters.

     Re-Introduced the mod_autoindex IndexOptions flag TrackModified
     from Apache 1.3.15.  This is needed for two reasons, first, given
     multiple machines within a server farm, ETags and Last-Modified
     stamps won't correspond from machine to machine, and second, many
     Unixes don't capture changes to the date or time stamp of existing
     files, since these don't modify the dirent itself.
     [Originally for 1.3 by me]

     Re-Introduced the mod_autoindex InextOptions flag FoldersFirst
     and DirectoryWidth options from Apache 1.3.10.

  A debatable change, to return (an absolute) 404 if some of the extentions

  Thanks goes to Manoj, while commenting on another issue, for triggering
  this idea.  If we find files matching (e.g. index.html.bak matches
  index.html) but they are rejected because we don't understand them
  (e.g. they are a directory, or .bak isn't a mod_mime recognized extension)
  then Error 500 out of here, with a note for the system administrator
  explaining that index.html matches some files, but their extensions
  cannot be grokked.  No more (unintentional, or situational) autoindex :)

  Subtle variation for security.  If the mod_mime file has nothing specific
  to say about a given set of file extentions (and has only based the
  resolved fields on the default language, encoding and content type)
  then tell us we can ignore the result by leaving the exception list
  entirely undefined.  If mod_mime adds anything (a language, charset, or
  whatnot) then proceed to use the file in the Multiviews evaluation,
  otherwise mod_negotation will ignore the file found.

  This points out a need for a slightly twisted DefaultClientLanguage,
  as opposed to creating foo.html.html files.  Either that, or introduce
  a 'neutral' entity that the user can list (say, .default) for mod_mime
  to declare it as a fallback language/encoding/content-type/handler.

  Solve the major underlying problem of content negotation by passing
  mod_negotiation the 'unresolved' parts of the path in a ->notes
  array ap-mime-exceptions-list.

  If mod_mime is given index.html.bad.en it will add index and bad
  to the list (presuming html and en are both defined.)

  mod_negotiation will decide if index and bad are it's fault (the
  user requested index.html.bad[.*]) or if it's a messed up file
  (say .old, .junk, or .bak).

  The next patch to allow any-order negotiation should check each
  of these list elements, so that asking for index.bad in the prior
  example would succeed.  Right now that request would fail because
  .html was recognized, so it's not in the exceptions list.  This
  patch uses a simple strcmp to the given name.

  Also, this patch allows any mod_mime processed file to be served,
  even if the content type cannot be determined (think README.en).
  This is crippled by the client expect headers and omitting the
  default content type.

  PLEASE vet this code carefully.

  Save hundreds of cycles on every autoindex request by _not_ attempting
  to to test the parent (..) sub request!  This patch also allows the user
  to see things that will redirect them.  That way, the lnk or dir within
  the directory is displayed correctly.

  Also allows an ALT text entry other than DIR by providing AddAlt
  ^^DIRECTORY^^, as the user (might) expect to be allowed to do.
