Thanks for the suggestions everybody.  I like Jari's bindings the
best, although the C-M arrow keys are already mapped by the window
manager.  Drop the Meta and they're almost as convenient as a
scrollbar.  :-)

I didn't intend this to be a frivolous question.  I only count 47
available characters with standard thread indentation and the standard
*Summary* format available for a first level subject.

I display the subject in the article-buffer's mode line (and suppress
it from displaying in the article itself; this saves 1 line in the
article-buffer); to date I haven't come across a subject that was
longer than 80 chars.

Never.

Besides the fact that I'm really not interested when in the Summary buffer,
here are the left/right scrolling commands that are built into emacs:

;;; 3/21/90         better calculation of w-width in e-make-point-visible
;;;                 test for truncated windows
;;;                 added substitute-in-keymap

;;; This is a rewrite of auto-horizontal.  It is comparable in functionality
;;; hscroll.el except it is not a minor mode and does not use any timers.
;;;
;;; This file provides functions that automatically scroll the window
;;; horizontally when the point moves off the left or right side of
;;; the window.  To enable, the variable truncate-lines must be
;;; non-nil -- truncate-lines becomes buffer-local whenever it is set..
;;; This causes long lines to disappear off the end of the screen instead of
;;; wrapping to the beginning of the next line.  To cause this to be the
;;; default for all buffers and to load this package, add the following lines
;;; to your .emacs (sans ;;;):
;;;
;;; (setq default-truncate-lines t)
;;; (require 'auto-show)

;;; I've found that I only want this when I'm editing C code.  Accordingly
;;; I have something like the following in my .emacs:
;;;
;;; (load-library "auto-show")
;;; (defun my-c-mode-hook ()
;;;   "Run when C-mode starts up.  Changes the comment column to be 40"
;;;   ... set various personal preferences ...
;;;   (setq truncate-lines t))
;;; (add-hook 'c-mode-hook 'my-c-mode-hook)

(provide 'auto-show)

In the summary we don't want to see it, and in the article buffer the
line wraps so all of it is visible.

And you can scroll the summary buffer horizontaly if you really want
to, but maybe you'd rather toggle truncation instead.

How do you all on Emacs see the right side of long subjects without a
horizontal scrollbar?
