I think this is a complete merge of the dired-details changes into  
dired. I've slightly changed the behavior to be more robust in  
various corner cases of dired. Notable changes are:

  1) dired-virtual now calls dired-after-readin-hook as it's last  
step. semantically this seems reasonable but perhaps there's a user  
of this hook somewhere out there who would be shocked.

  2) there are three key mappings for this mode: '(' -> dired-details- 
hide, ')' -> dired-details-show, ';' -> dired-details-toggle. Three  
keys worth of real estate in the dired map may be too expensive -- I  
think it's nice to use ( and ) to hide and show but others wanted a  
toggle key.

Aside from that, it's had a whole week of testing !

+   @dfn{Hiding} file details means making file attributes and symbolic
+ link targets invisible using overlays (@pxref{Overlays,,, elisp, the
+ Emacs Lisp Reference Manual}). This converts the dired display to a
+ terse list of filenames while continuing to support all normal dired
+ commands.
+ 
+ @table @kbd
+ @item @kbd{;}
+ @findex dired-details-toggle
+ @kindex @kbd{;} @r{(Dired)}
+ Hide or reveal file details in the current Dired buffer.
+ 
+ @item @kbd{(}
+ @findex dired-details-hide
+ @kindex @kbd{(} @r{(Dired)}
+ Hide file details in the current Dired buffer.
+ 
+ @item @kbd{)}
+ @findex dired-details-hide
+ @kindex @kbd{)} @r{(Dired)}
+ Show file details in the current Dired buffer.
+ @end table
+ 
+    You can customize @code{dired-details-hidden-string} to display any
+ string in place of hidden details and link targets (the default is
+ "[...]").
+ 
+    The option @code{dired-details-hide-link-targets} can be set to
+ @code{nil} to show link targets when details are hidden. The default is to
+ hide link targets.
+ 
+    Currently, the dired-sort-* family of functions do not call
+ @code{dired-after-readin-hook} and thus will not hide details until
+ the next call to @code{dired-revert} (@kbd{g}).
