dired listg & dired-sort-menu.el

[Harry Putnam]

   Running 
   Emacs 24.0.92.1 on Debian (testing)

Just tinkering with the sorting in dired and ran across Francis J
Wright's 'dired-sort-menu.el' (and menu+)... The following site shows
the menu that is produced:

  http://www.emacswiki.org/emacs/DiredSortMenu

But when I load the library and press 'M-x dired-sort-dialogue' I get
a less extensive menu and wondered if this is a result of the library
being quite old (or possibly changes in the gnu 'ls' command..) 

  ( dired-sort-menu.el,v 1.26 2001-07-26 21:22:48+01 )

compared to the emacs version I'm running or if
I've done something to cause this.

If it matters I tried with and without dired-x.
