bug#445: Invalid read syntax in savehist-mode's history file

[Daniel Colascione]

I found this line in my ~/.emacs.d/history. I've trimmed the list to
include only the problematic element and formatted it for email.

(setq command-history
      ...  
      '(describe-key-briefly
        '[mode-line (down-mouse-1
                     (#<window 199> mode-line (110 . 617)
                               -97640112
                               ("Calc: 12 Deg               " . 6)
                               41 (13 . 47) nil (5 . 9) (8 . 16)))] nil 1)
      ...)

The lisp reader complains about the #<window 199>.
