So the code here is:

(defun edebug-next-token-class ()
[...]
  (if (and (eq (following-char) ?.)
           (save-excursion
             (forward-char 1)
             (or (and (eq (aref edebug-read-syntax-table (following-char))
                          'symbol)
                      (not (= (following-char) ?\;)))
                 (memq (following-char) '(?\, ?\.)))))

So it's explicitly allowing , after . here -- but surely that's wrong?
Or are there any circumstances that reading .,<foo> leads should lead to
a valid symbol?  Juri, do you remember this?  It's from 2004.  😀
