Re: c-like comments settings

[drain]

Very lazy hint: take a look at the comment-region source code:

(defun comment-region (beg end &optional arg)
  "Comment or uncomment each line in the region.
With just \\[universal-argument] prefix arg, uncomment each line in region
BEG .. END.
Numeric prefix ARG means use ARG comment characters.
If ARG is negative, delete that many comment characters instead.

The strings used as comment starts are built from `comment-start'
and `comment-padding'; the strings used as comment ends are built
from `comment-end' and `comment-padding'.

By default, the `comment-start' markers are inserted at the
current indentation of the region, and comments are terminated on
each line (even for syntaxes in which newline does not end the
comment and blank lines do not get comments).  This can be
changed with `comment-style'."
  (interactive "*r\nP")
  (comment-normalize-vars)
  (if (> beg end) (let (mid) (setq mid beg beg end end mid)))
  (save-excursion
    ;; FIXME: maybe we should call uncomment depending on ARG.
    (funcall comment-region-function beg end arg)))
