* Lisp Changes in Emacs 21.4
+** When using non-toolkit scroll bars with the default width,
+the scroll-bar-width frame parameter value is nil.
+
+** The new function copy-abbrev-table returns a new abbrev table that
+is a copy of a given abbrev table.
+
+++
** The option --script FILE runs Emacs in batch mode and loads FILE.
It is useful for writing Emacs Lisp shell script files, because they
are used by define-derived-mode to make sure the mode hook for the
parent mode is run at the end of the child mode.
+** define-derived-mode by default creates a new empty abbrev table.
+It does not copy abbrevs from the parent mode's abbrev table.
+
+++
** `provide' and `featurep' now accept an optional second argument
to test/provide subfeatures. Also `provide' now checks `after-load-alist'
** `define-key-after' now accepts keys longer than 1.
-** `define-derived-mode' now accepts nil as the parent.
-
** The local variable `no-byte-compile' in elisp files is now obeyed.
** The Emacs Lisp byte-compiler now displays the actual line and
