;; vim outline

Eval the next 2 expressions in the buffers context.

;; (set (make-local-variable 'outline-regexp)  ".*{{{\\([0-9]+\\)")
;; (set (make-local-variable 'outline-level) 'vim-outline-level)

(defun vim-outline-level ()
  (save-excursion
    (re-search-forward "{{{\\([0-9]+\\)" nil t)
    (string-to-number (match-string 1))))
