Feedback on etc/* documents, mostly copyrights

["Andrew M. Scott" <amscott1@sedona.ch.intel.com>]

1. The first line of etc/NEWS has a spurious date in it:

GNU Emacs NEWS -- history of user-visible changes.  2003-05-21
                                                    ^^^^^^^^^^
2. Is there a reason that

    etc/NEWS,MH-E-NEWS,GNUS-NEWS,DEBUG,DISTRIB,GNU,

    have copyright date lines, but 

   etc/MORE.STUFF,PROBLEMS,TODO,CENSORSHIP,MACHINES,grep.txt,compilation.txt,
   MAILINGLISTS,ETAGS.EBNF,.arch-inventory,HELLO,SERVICE,Xkeymap.txt,ctags.1,
   emacs.csh,ledit.l,ms-7bkermit,ses-example.ses,ulimit.hack,MOTIVATION,LPF,
   TERMS,WHY-FREE,README,ORDERS,FTP

   do not? 

   There are also files with older than 2006 copyrights (see #3-11).
   If there is a good reason for these, maybe there should be some way
   that a batch copyright-update process could DTRT if run on the
   whole directory.

3. Is there a reason the -*-outline-*- in the first line of etc/TODO
   is so far to the right side? It may because it was copied from
   etc/ERC.

4. The Copyright in etc/INTERVIEW is only 1986

5. The Copyright in etc/COPYING is 1981,1991

6. etc/enriched.doc has 1995, 1997 dates but not a real copyright line

7. ONEWS and ONEWS.1-4 have older copyright dates.

8. OTHER.EMACSES has a 1985 copyright date

9. ledit.l - There are no descriptive comments
   at the top. I do see it mentioned in LEDIT.

10. ms-kermit has May 13, 1990 date but no copyright.

11. LINUX-GNU has a 1996, 2002 copyright

12. It's hard to believe spook.lines hasn't been updated since 1999.
