user has no relief (other than lynx) when text is too wide

[jidanni@xxxxxxxxxxx]

http://kml4earth.appspot.com/kmlBestPractice.html goes off the edge of
the screen and there is nothing the user can hit to fix it.

My screen is *only* 123 characters wide.

P.S., after the latest snapshot,

(add-hook 'w3m-mode-hook
	  (lambda ()
	    (define-key w3m-mode-map "\M-t" 'w3m-redisplay-invert-render-table)
	    (define-key w3m-mode-map "\M-T" 'w3m-redisplay-toggle-render-table))))

(defvar w3m-no-render-table nil
  "*If non-nil, do not render any table tag.")
(defun w3m-redisplay-invert-render-table (&optional arg)
  (interactive "P")
  (let ((w3m-no-render-table (not w3m-no-render-table)))
    (w3m-redisplay-this-page arg)
    (message (format "Display with%s rendering table"
		     (if w3m-no-render-table " NO" "")))))

(defun w3m-redisplay-toggle-render-table (&optional arg)
  (interactive "P")
  (setq w3m-no-render-table (not w3m-no-render-table))
  (w3m-redisplay-this-page arg)
  (message (format "Change redering table to %s"
		   (if w3m-no-render-table "nil" "TRUE"))))

(eval-after-load "w3m-filter"
  '(nconc w3m-filter-rules '((".*" w3m-filter-no-render-table))))

(defun w3m-filter-no-render-table (&optional url)
  (when w3m-no-render-table
    (let ((case-fold-search t))
      (goto-char (point-min))
      (while (re-search-forward "</?\\(table\\)[ \t\r\f\n>]" nil t)
	(goto-char (match-beginning 1))
	(insert "NO_"))
      (goto-char (point-min))
      (while (re-search-forward "<\\(tr\\)[ \t\r\f\n>]" nil t)
	(goto-char (match-beginning 1))
	(insert "NO_")
	(goto-char (match-beginning 0))
	(insert "<br>"))
      (goto-char (point-min))
      (while (re-search-forward "</\\(tr\\)>" nil t)
	(goto-char (match-beginning 1))
	(insert "NO_")))))

doesn't work either.
