This is related with an issue discussed in another thread
(require-hard-newlines to use newline), but is more general.
In Emacs 21.3, Text mode did not override the default value of
require-final-newline. In current CVS, it does via
mode-require-final-newline. Is there a reason for that? I can see a
reason for some specific derived modes, but these derived modes could
use mode-require-final-newline themselves, instead of letting the
parent mode do it for them.
Also, nil _is_ a valid value for mode-require-final-newline. But the
docstring is not very explicit about that and you can not set it to
nil via Custom. If you set it to nil outside Custom, Custom will
falsely describe the value as `ask', which is a bug. Would it be good
to have the docstring mention this explicitly and allow it to be set
to nil via Custom with proper warning of the involved dangers (which
would fix the bug)?
Sincerely,
Luc.

I don't remember the reason, but I remember there was one.
I think that specific point was discussed in this list
a few months ago.

I don't know how to make Custom issue warnings.

I don't remember the reason, but I remember there was one.
I think that specific point was discussed in this list
a few months ago.
Actually, the decision to replace the old _way_ to override the
default value of `require-final-newline' with a new one based on
`mode-require-final-newline' was made a few months ago. Maybe I
caused confusion by mentioning `mode-require-final-newline'. I was
not asking about the _implementation change_. The real question I
wanted to ask was:
In Emacs 21.3, Text mode did not override the default value of
require-final-newline. In current CVS, it does. Is there a
reason for that?
Here, the relevant change was made more than two years ago:
2002-09-02 Stefan Monnier <monnier@cs.yale.edu>
* textmodes/text-mode.el
(paragraph-indent-text-mode-abbrev-table)
(paragraph-indent-text-mode-syntax-table,
paragraph-indent-text-mode):
Use text-mode's syntax-table and abbrev-table.
(text-mode): Set require-final-newline to t.
Sincerely,
Luc.

Hmmm... I didn't expect my name to show up here.
I must say I can't remember why I set require-final-newline to t there.
And in retrospect and given all the discussions about require-final-newline,
I wouldn't mind if someone reverts this part of the above change.

I don't know how to make Custom issue warnings.
I meant putting a warning message in the Custom buffer if nil is
chosen from the value menu, using the :doc keyword. But on second
thought, I do not believe that such a warning is necessary. The
docstring of `mode-require-final-newline' already says:
Those modes set `require-final-newline' to this value when you enable
them. They do so because they are used for files that are supposed to
end in newlines, and the question is how to arrange that.
If the user sets the option to nil, he knows that he chooses to
arrange for that by remembering to do it manually (or by using
software that can handle files without final newline).
Sincerely,
Luc.

I think we did discuss that question leading up to my decision
to introduce mode-require-final-newline. However, there is
probably more discussion in August or September 2002.

I have the following in my .emacs:

It would be better if org mode did this automatically. There is
a facility specifically for this:
| mode-require-final-newline is a variable defined in `files.el'.
|
| Documentation:
| Whether to add a newline at end of file, in certain major modes.
| Those modes set `require-final-newline' to this value when you enable them.
| They do so because they are often used for files that are supposed

|
| A value of t means do this only when the file is about to be saved.
| A value of `visit' means do this right after the file is visited.
| A value of `visit-save' means do it at both of those times.
| Any other non-nil value means ask user whether to add a newline, when saving.
|

I posit that org-mode should set this variable to nil.

I do not yet see what the problem is. Why is this annoying you?

It annoys me because the ... indicate that text is being hidden, but
in fact the only hidden data is a single newline.

To be honest, I am not sure that this is the right solution. For some
operations in org-mode, like structure editing, that final newline is
good to have. Also, this issue with the final newline is depending on
personal preferences.
I tend to believe that the better solution is to fix outlining, so that
it will never hide empty lines at the end of the buffer. Hope you can
agree if I implement that latter solution.

Certainly. Now you point it out, I agree that is the "more correct"
