Changelog: Showing Dates From 1986

Changelog: Showing Dates From 1986

[raman]

After a git pull (has been true since Apr 7 I think)
Changelog  entries are showing with dates from the dim distant  past
e.g.
1986-05-05  Richard M. Stallman  (rms@prep)

	* isearch.el (isearch):
	Fix bug extending a search string in place
	in reverse regexp search.

1986-05-02  Richard M. Stallman  (rms@prep)

	* mh-e.el (mh-get-field): Make regexp accept values starting
	with non-letters.

Sorry, I put the wrong gen_origin value into Makefile.in.  I think this is 
because I tested 'make ChangeLog' and 'make change-history' in a private branch, 
and then applied the corresponding patch to the master without thinking about 
the checksum disparity.  I installed the attached to fix this and to try to make 
similar glitches less likely in the future.

Subject: [PATCH] Improve 'make change-history' prereq tests

* Makefile.in (gen_origin): Fix to match what's in the master branch.
(no-ChangeLog, master-branch-is-current): New rules.
(change-history): Depend on them, to avoid similar future problems.
Escape the local-variables string to pacify Emacs when editing
Makefile.in.
