You need to look at the actual doc string, not its source: If non-nil, regular expression to match a sequence of whitespace chars. When you enter a space or spaces in the incremental search, it will match any sequence matched by this regexp. As an exception, spaces are treated normally in regexp incremental search if they occur in a regexp construct like [...] or *, + or ?. If the value is a string, it applies to both ordinary and regexp incremental search. If the value is nil, or ‘isearch-lax-whitespace’ is nil for ordinary incremental search, or ‘isearch-regexp-lax-whitespace’ is nil for regexp incremental search, then each space you type matches literally, against one space. You might want to use something like "[ \t\r\n]+" instead. In the Customization buffer, that is ‘[’ followed by a space, a tab, a carriage return (control-M), a newline, and ‘]+’. Don’t add any capturing groups into this value; that can change the numbering of existing capture groups in unexpected ways. -- Andreas Schwab, schwab@linux-m68k.org GPG Key fingerprint = 7578 EB47 D4E5 4D69 2510 2552 DF73 E780 A9DA AEC1 "And now for something completely different."
