Bug#945337: why is the version from elpa needed

[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

OK, working with
$ apt-cache policy emacs
emacs:
  Installed: 1:27.1+1-3
  Candidate: 1:27.1+1-3
  Version table:
 *** 1:27.1+1-3 990
        990 http://opensource.nchc.org.tw/debian unstable/main amd64 Packages
tramp-version is a variable defined in ‘tramp-cmds.el’.
Its value is "2.4.3.27.1"

I.e., already about 11 versions deep on
https://elpa.gnu.org/packages/tramp.html

What's worse is:
A debian users visits
https://elpa.gnu.org/packages/tramp.html
and sees
To install this package, run in Emacs:
M-x package-install RET tramp RET
but as debian already has an old tramp,
so underneath his fingertips this expands to
tramp-theme !!!!
and unless he notices what happened,
he still can't advance beyond the old tramp version!
All he has done is install tramp-theme, not tramp.

Also
$ aptitude search elpa-|wc -l
343
$ w3m -dump -cols 999 https://elpa.gnu.org/packages/index.html|perl -nwle 'print if /^a/../^$/'|wc -l
276

So there are more elpa- packages in Debian than even on the official
elpa website!

Therefore I propose that all packages on the elpa website be
automatically included in Debian.
