'(compare-ignore-whitespace t) in customisation makes compare-windows crash in GNU Emacs 23.0.0

[Peter Dyballa]

Hello!

It's only in GNU Emacs 23.0.0 that this customisation leads to this  
error message:

	Debugger entered--Lisp error: (wrong-number-of-arguments #[nil "À  
\210Á\207" [compare-windows-skip-whitespace t] 1] 1)
          #[nil "À  \210Á\207" [compare-windows-skip-whitespace t] 1](1)
          compare-windows(nil)
          call-interactively(compare-windows)

Commenting '(compare-ignore-whitespace t) makes the error go away.

Proof: launch with -Q. Open two buffers, for example file and file~.  
Perform the comparison. Put

        (setq compare-ignore-whitespace t)

into the *scratch* buffer and evaluate the expression or set by some  
other means compare-ignore-whitespace to t. But the point in the two  
buffers again on start and re-compare.

It does *not* happen with GNU Emacs 22.0.50! Source is about five  
days old.
