 @section Subdirectory Switches in Dired
 
 You can insert subdirectories with specified @code{ls} switches in
-Dired buffers, using @kbd{C-u i}.  You can change the @code{ls}

 switches of an already inserted subdirectory using @kbd{C-u l}.
 
-In Emacs versions 22.1 and later, Dired remembers the switches, so

-directory's switches.  Deleting a subdirectory forgets about its
-switches.

 can easily correct the situation using @kbd{C-u i} or @kbd{C-u l}.

 For instance, updating or killing a subdirectory that was inserted
