Package:  emacs
Severity: minor

	As of 84b50168 [1], C-h p C-s games RET lists only a few games
	of those coming with Emacs:

  Package            Version      Status ▼   Archive    Description
  dunnet             2.1          built-in              text adventure for Emacs
  gamegrid           1.2          built-in              library for implementing grid-based games on Emacs
  tetris             2.1          built-in              implementation of Tetris for Emacs

[1] http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=84b50168

	As it seems, package-show-package-list is given all the games
	found, yet it fails to render them in the resulting *Packages*
	buffer, perhaps because of them missing the Version: metadata.

	As per M-x trace-function-background:

1 -> (package-show-package-list (zone tetris studly spook solitaire snake pong mpuz morse meese life landmark hanoi gomoku gametree gamegrid fortune dunnet doctor dissociate decipher cookie1 bubbles blackbox animate 5x5))
1 <- package-show-package-list: #<buffer *Packages*>

	As per M-x trace-function-background:

package.el was designed to handle installation of packages that are
separate from Emacs.   It can also deal with packages that are bundled
with Emacs, but only if those announce themselves as such.

	To me, the failure of the recent development version to show the
	above seems like a regression, regardless of the particulars.

	If the change made to package.el was indeed intended, then my
	guess is that it should’ve been complemented with the changes to
	all of the packages above to make them fit the newly imposed
	criteria for inclusion.

Oh, right, sorry.  I didn't realize that finder already used package.el
in 24.3 to display the packages.  Hmm...

The change was more along the lines that there's no point showing those
packages in package.el because there's nothing the user can do with them
in terms of install/update/uninstall (by virtue of being built-in and
having no version number).

But indeed, I see now that package.el was also used by finder as a kind
of browser to get at the package's Commentary, in which case those
unversioned packages can still be useful.

Hmm....

	I no longer observe the issue (as of 2014-11-18 build,
	cb4f666ade76.)  Per my reading of the Git log, it was fixed
	(as Bug#16762) in the emacs-24 branch back this March:

commit 3e2377ce2f4eeb141ffbd000723c55813f78b08f
Author:     Dmitry Gutov <dgutov <at> yandex.ru>
AuthorDate: Tue Mar 25 00:38:06 2014 +0200
Commit:     Dmitry Gutov <dgutov <at> yandex.ru>
CommitDate: Tue Mar 25 00:38:06 2014 +0200

    Fix bug#16762
    
    * lisp/emacs-lisp/package.el (package--add-to-archive-contents):
    Include already installed and built-in packages in
    `package-archive-contents'.
    (package-install): Don't include already installed packages in the
    options on interactive invocation.
