[PATCH] maint: add coding cookies to non-ASCII sources

[Paul Eggert]

Otherwise, Emacs might do the wrong thing if run in an
he_IL.ISO-8859-8 locale, which an Emacs developer does on occasion.
Problem reported by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00966.html

Don't bother with test files, as they aren't copied to the Emacs
source directory.  If this problem affects test files in some other
GNU project, we can add coding cookies to the non-ASCII test files
later.
