  maint: add coding cookies to non-ASCII sources
  
  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.
