here is a change to have C-n not move past eob.  put it in your .emacs
if you like it.  use C-xC-e at the end of it to try it for the rest of
your emacs session.

p.s.  symbolics machines use keywords to allow this.  will elisp gain
keywords?

(defun next-line (arg)
  "Local version of the command.  Does not insert newlines.  Only one line
has changed.

	Move cursor vertically down ARG lines.
If there is no character in the target line exactly under the current column,
the cursor is positioned after the character in that line which spans this
column, or at the end of the line if it is not long enough.
If there is no line in the buffer after this one,
a newline character is inserted to create a line
and the cursor moves to that line.

The command \\[set-goal-column] can be used to create
a semipermanent goal column to which this command always moves.
Then it does not try to move vertically.

If you are thinking of using this in a Lisp program, consider
using `forward-line' instead.  It is usually easier to use
and more reliable (no dependence on goal column, etc.)."
