I'm using msf-abbrev [1] library which uses emacs-lisp-mode-abbrev-table for 
emacs-lisp-mode and this mechanism worked in emacs 23.2 and not in emacs 
24.0.50. Now I modified msf-abbrev settings to use lisp-mode-abbrev-table but 
in fact it can be misleading to see emacs-lisp-mode-abbrev-table not working 
with emacs-lisp-mode. It's better to remove this table or explain how to use 
this abbrev table in emacs and elisp manuals. 

Thanks,

Seweryn
