I think you're being confused by the way customize treats regexps (it
confuses me as well; I'm not sure it is helpful). There is extra
escaping in the setting of search-whitespace-regexp that is written to
your .emacs. It should be:
'(search-whitespace-regexp "[ \t\r\n]+"))
The doc of search-whitespace-regexp says:
In the Customization buffer, that is `[' followed by a space,
a tab, a carriage return (control-M), a newline, and `]+'
If you literally use that input, does it work?
Oh, it's not possible to type a TAB, or ctrl-M, or newline, in a custom
field, since it moves you out of the editable field... This is even more
confusing.
