message:
Make ordinary isearch obey search-whitespace-regexp too.
* lisp/isearch.el (search-whitespace-regexp): Make string and nil
values apply to both ordinary and regexp search. Allow a cons
cell value to distinguish between the two.
(isearch-whitespace-regexp, isearch-search-forward)
(isearch-search-backward): New functions.
(isearch-occur, isearch-search-fun-default, isearch-search)
(isearch-lazy-highlight-new-loop): Use them.
(isearch-forward, isearch-forward-regexp): Doc fix.

and `M-s _' in Isearch toggles symbol search mode.
`M-s c' in Isearch toggles search case-sensitivity.
+*** `search-whitespace-regexp' now acts on ordinary incremental search
+as well, so that each sequence of spaces in the search string matches
+any combination of one or more whitespace characters. To change this
+behavior, you can give `search-whitespace-regexp' a cons cell value,
+where the car and cdr specify values for ordinary and regular
+expression incremental search respectively.
+
** M-x move-to-column, if called interactively with no prefix arg, now
prompts for a column number.
