@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}
+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
-that reverting the buffer will not change them back to the main
-directory's switches. Deleting a subdirectory forgets about its
-switches.
+Dired preserves the switches if you revert the buffer. Deleting a
+subdirectory forgets about its switches.
Using @code{dired-undo} (usually bound to @kbd{C-_} and @kbd{C-x u})
-to reinsert or delete subdirectories, that were inserted with explicit
-switches, can bypass Dired's machinery for remembering (or forgetting)

forget its switches. When later reinserted using @kbd{i}, it will be
reinserted using its old switches. Using @code{dired-undo} to

Dired commands (not @code{dired-undo}) will originally insert it with

the buffer's default switches. If any of this yields problems, you
can easily correct the situation using @kbd{C-u i} or @kbd{C-u l}.
Dired does not remember the @code{R} switch. Inserting a subdirectory

inserting each of its subdirectories using all remaining switches.
For instance, updating or killing a subdirectory that was inserted
with the @code{R} switch will not update or kill its subdirectories.
The buffer's default switches do not affect subdirectories that were
inserted using explicitly specified switches. In particular,

You can make Dired forget about all subdirectory switches and relist
