/usr/local/share/emacs/site-lisp is not expanded on ubuntu installs

Hi, 

On Ubuntu the directories of /usr/local/share/emacs/site-lisp are not
added to load-path as stated in the documentation:


   
      If `EMACSLOADPATH' is not set (which is usually the case), Emacs
   initializes `load-path' with the following two directories:
   
        "/usr/local/share/emacs/VERSION/site-lisp"
   
   and
   
        "/usr/local/share/emacs/site-lisp"
   
   [...]
   
      Next, Emacs "expands" the initial list of directories in `load-path'
   by adding the subdirectories of those directories.  Both immediate
   subdirectories and subdirectories multiple levels down are added.  But
   it excludes subdirectories whose names do not start with a letter or
   digit, and subdirectories named `RCS' or `CVS', and subdirectories
   containing a file named `.nosearch'.


I see the same thing on emacs23, emacs24 and emacs-snapshot on Kubuntu
13.04.

The path /usr/share/emacs/site-lisp is expanded. Does this mean that
/usr/share/emacs/site-lisp should be used for the installation of add-on
packages? If so, then the info page should be updated.


Thanks,
