C-x C-b (list-buffers) shows each buffer's major mode.

Try: C-h a -mode\'

(The minor-modes line is telling you that the symbol is interned in the
standard obarray, but it has no value or function binding.)

stop rewriting Message-IDs

[Dan Jacobson]

Dear bug-gnu-emacs: again: for RFC compliant Message-IDs, there is no
reason for bug-gnu-emacs's mailman to rewrite them.

For instance, here reading from gmane.org NNTP, my message has
References: <mailman.443.1064004252.21628.bug-gnu-emacs@gnu.org>
	<3F6F155C.4010606@yahoo.com>

however mailman.443.1064004252.21628.bug-gnu-emacs@gnu.org is how my
article looks to Kevin, but that article can't be found on gmane. The article's
original rightful Message-ID is what is on gmane.

There is no justification for rewriting Message-IDs other than being
too lazy to use a regexp to see if the Message-IDs is RFC compliant.
And it's creating a big mess.

I sent a message to the maintainers last year.

I meant a list of all the modes in effect for this buffer.  Yes, there
they are mostly in the modeline, but how about a lisp list?

OK, C-h a -mode$
looks simpler for me.

If you need it, you could write it yourself:

(defun buffer-mode-list ()
   "Return a list of the current buffer's major mode and minor modes."
   (interactive)
   (let ((modes (cons major-mode
                      (apply 'nconc
                             (mapcar (lambda (key-value)
                                       (let ((variable (car key-value)))
                                         (if (and (boundp variable)
                                                  (symbol-value variable))
                                             (list (symbol-name variable)))))
                                     minor-mode-alist)))))
     (if (interactive-p)
         (message "%s" modes)
       modes)))

But won't return symbols with a newline in their name.  :-)

It will, and it may match even more than the first.

describe-mode should first summarize all modes in effect

[Dan Jacobson]

Indeed, emacs lacks a command to show concisely what all those mode
abbreviations crammed in the modeline stand for.  There should be a
function explain-modeline-modes, that puts them in the minibuffer.
Kevin's function below could be enhanced to do that.

Better yet, have describe-mode output Kevin's  list at the top of its
output, before getting mired in detail.

I don't think that's necessary.  Everything is explained in the "Mode
Line" and "Minor Modes" sections of the Emacs manual.  And `C-h m'
already lists each minor mode indicator:

| The major mode is described first.
| For minor modes, see following pages.
|
| Emacs-Lisp mode:
| Major mode for editing Lisp code to run in Emacs.
...
| \f
| Eldoc minor mode (indicator ElDoc):
| *Enable or disable eldoc mode.
...

dusty manual can tell one what SC MML MC-w Fly ... expand to?

_pages_... scattered miles and miles later, ^L or no ^L.
Why not summarize first?
RMS sent a probable improvement, but not to this list.
