comment.el 2.0

[Andreas Röhler]

Hi all,

set out to fix a bug occuring in all Emacsen, reported at

http://tracker.xemacs.org/XEmacs/its/issue232

it ended up with an alternative comment.el.

Call `comment-c-test-lor' to see how it proceeds.

The bug of `indent-new-comment-line' should be gone
with the following key:

(global-set-key [(meta j)] 'comment-indent-new-line-lor)

With `c-toggle-comment-style' both C comment-styles
are available.

A call to `comment-dwim-lor' or `comment-uncomment-lor'
from inside a comment which spans over several lines
should uncomment.

With universal arg, line or region is copied and
inserted over commented part, thus
preserving old state.

Comment.el should not disturb newcomment.el; it's
suffix `-lor' means `line-or-region', designing a
new feature: If no active region exists, all
commands operate from current line.

Other main diffs to newcomment.el are:

Styles will not be chosen by customization, but
called with respective functions.

Checks for a comment-char found inside a string no
longer relies on fontifying.

The following kinds of commands should be available:

;;                         comment-uncomment
;;                                 /\
;; (copy/do-not-copy)             /  \
;;                               /    \
;;                        comment      uncomment
;;                       /\                    /\
;;                      /  \                  /  \
;;                     /    \                /    \
;;                plain      indent       all    not-all
;;               /\               /\
;;              /  \             /  \
;;             /    \           /    \
;;     span-line  single    span-line single 
;;        /\        /\        /\        /\
;;       /  \      /  \      /  \      /  \
;;      /    \    /    \    /    \    /    \
;;
;;  ------------ boxed not-boxed ----------------



Caveat: Uncomment... detects only selected
comment-style, i.e. "/* */" or "//" in C. When
uncommenting, make sure the appropriate style is
switched on.

So far
