Convert some files from outline-mode to org-mode

[Stefan Kangas]

In Bug#40813, I suggest the following:

    * CONTRIBUTE:
    * etc/CALC-NEWS:
    * etc/DEBUG:
    * etc/MACHINES:
    * etc/PROBLEMS:
    * etc/TODO: Use org-mode instead of outline-mode.

The reason is that I believe our users are more familiar with org-mode
than outline-mode, and that I simply think the interface is better.
It's the forward-looking, "modern" choice, if you like.

This was not met with undivided enthusiasm, and the suggestion was to
bring the discussion here.

Here's my attempt to summarize the counter-arguments:

(1) Outline-mode is in fact more well-known than org-mode.
(2) Org-mode increases memory consumption (by 1-3 MB).
(3) We could improve outline-mode by adding something like org-cycle (TAB).
(4) There's a slight delay when opening an org file for the first time
in a session.

I would say that (1) is hard to prove or disprove, and I have only
anecdotal evidence here.  Regarding (2), this is true but I disagree
that it's significant enough to worry about in this day and age.  It's
hard to argue against (3) but it needs an interested party to do it.
Finally, I don't know if anything can be done about (4).

So please make it known how you feel about this proposal.

Best regards,
Stefan Kangas
