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.
