making tables from free-form data

I love the emacspeak table browsing mode but I found a little
difficulty generating data in the right format for the various set-up
functions.  So I hacked Raman's comma-separated-value reading code to
use awk to generate the correct format.  As it stands the code will
break each line into fields delimited by wite-space. 
Feel free to correct bugs or suggest improvements

(defun emacspeak-table-make-table-in-buffer (&optional buffer-name)

navigation. "
  (or buffer-name
      (setq buffer-name (current-buffer)))
  (let ((scratch (get-buffer-create "*table-scratch*"))
        (table nil)
        (buffer (get-buffer-create
                 (format "*%s-table*" buffer-name))))
      (set-buffer scratch)
      (insert-buffer buffer-name)
      (goto-char (point-min))
; now make sure any quotes are properly escaped
      (while (search-forward "\"" nil t)
