[ESS] outline-minor-mode

[Heinz Tuechler]

More than a year later and with the help of Stefan Monnier at
help-gnu-emacs, I found one way to adapt outline-minor-mode to R-comments.
A first line in an R-syntax file like the following has the effect to treat
comments with ##### as level 1 headlines, #### as level 2 headlines, and
### as level 3 headlines.

#### -*- mode: R ; mode:outline-minor; outline-regexp:"#\\{2,5\\} ";
outline-level: (lambda () (interactive) (cond ((looking-at "##### ")
1)((looking-at "#### ") 2)((looking-at "### ") 3)((looking-at "## ") 4)  (t
1000))) -*-

Together with outline-magic this is convenient for me.
