  To: 54230


In the documentation for the 'search-whitespace-regex':

Actual:

> You might want to use something like "[ \\t\\r\\n]+" instead.

Expected:

> You might want to use something like "[ \t\r\n]+" instead.

Just the "expected" version works:

;; Make Isearch search across spaces, tabs, and newlines.
(setq isearch-lax-whitespace t
      isearch-regexp-lax-whitespace t
      search-whitespace-regexp "[ \t\r\n]+")
