Documentation

If non-nil, regular expression to match a sequence of whitespace chars.

This applies to Info search for regular expressions. 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.
