  Fix bug #16216 with 'name' Unicode property of control characters.
  
   admin/unidata/unidata-gen.el (unidata-split-name): Don't give any NAME
   to <control> characters: the Unicode Standard says they have no
   name.
  
   doc/lispref/nonascii.texi (Character Properties): NAME or OLD-NAME
   properties can be nil (there's no empty string).
