Not sure about auto-format, but I highlight (my warning face is red)
the part of lines that extend past 80 characters using this:
(defun my-font-lock-prepends (mode)
"Adds a 80 character line-width"
(font-lock-add-keywords
mode
'(("\\(.\\{80\\}\\)\\(.+\\)"
2 font-lock-warning-face prepend))))
(my-font-lock-prepends 'jde-mode)
