Would you please eval the following forms and let me know if everything
works as expected?


(cl-defmethod ebdb-read ((field (subclass ebdb-field-tags)) &optional slots obj)
  (let* ((crm-separator (cadr (assq 'ebdb-field-tags ebdb-separator-alist)))
	 (val (completing-read-multiple
	       (format "Tags (separate with \"%s\"): " crm-separator)
	       ebdb-tags
	       nil nil
	       (when obj (ebdb-string obj)))))
    (cl-call-next-method field (plist-put slots :tags val))))


(cl-defmethod ebdb-fmt-field :around ((_fmt ebdb-formatter-ebdb)
				      (field ebdb-field)
				      _style
				      (_record ebdb-record))
  "Put the 'ebdb-field text property on FIELD.  The value of the
property is the field instance itself."
  (let ((str (cl-call-next-method)))
    (propertize (if (or (null str)
			(string-empty-p str))
		    "<empty>"
		  str)
