I don't see that emacs-lisp-mode-abbrev-table has ever had an effect.
In 23.1 it is void. In 23.2 and on it is defined (by define-derived-mode)
but not used. `add-mode-abbrev' in an Emacs Lisp mode buffer adds to
lisp-mode-abbrev-table. Adding an entry to emacs-lisp-mode-abbrev-table
in abbrev_defs has no effect.

This is because emacs-lisp-mode calls lisp-mode-variables, which
explicitly sets the abbrev-table to lisp-mode-abbrev-table.

To me, the bug looks like the fact that emacs-lisp-mode-abbrev-table is
defined at all. If it's never going to be used, the definition of
emacs-lisp-mode should specify an :abbrev-table.
