* Changes in Emacs 21.2
** When pure storage overflows while dumping, Emacs now prints how
much pure storage it will approximately need.
** M-x setenv now expands environment variables of the form `$foo' and
`${foo}' in the specified new value of the environment variable. To
include a `$' in the value, use `$$'.
** New user option `inhibit-startup-buffer-menu'.
When loading many files, for instance with `emacs *', Emacs normally
displays a buffer menu. This option turns the buffer menu off.
** Rmail now displays 5-digit message ids in its summary buffer.
* Lisp Changes in Emacs 21.2
** Variable aliases have been implemented
- Macro: defvaralias ALIAS-VAR BASE-VAR
This defines the symbol ALIAS-VAR as a variable alias for symbol
BASE-VAR. This means that retrieving the value of ALIAS-VAR returns
the value of BASE-VAR, and changing the value of ALIAS-VAR changes the
value of BASE-VAR.
- Function: indirect-variable VARIABLE
This function returns the variable at the end of the chain of aliases
of VARIABLE. If VARIABLE is not a symbol, or if VARIABLE is not
defined as an alias, the function returns VARIABLE.
It might be noteworthy that variables aliases work for all kinds of
variables, including buffer-local and frame-local variables.
** Functions from `post-gc-hook' are run at the end of garbage
collection. The hook is run with GC inhibited, so use it with care.
