* Changes in Emacs 21.4
** The new variable search-whitespace-regexp controls how to search
for spaces in a regular expression. If it is non-nil, it should be a
regular expression, and any series of spaces stands for that regular
expression. If it is nil, spaces stand for themselves.
Spaces inside of constructs such as [..] and *, +, ? are never
replaced with search-whitespace-regexp.
** line-move-ignore-invisible now defaults to t.
** In Outline mode, hide-body no longer hides lines at the top
