Subject: [PATCH] * mu-register.el (mu-cite-load-registration-file): Reverted.
  I've got XEmacs  wrong that it does'nt support the coding
 system magic cookie.  However it has  been working since
 XEmacs 21.2.21.  Users can avoid mis-decoding a file by 
 setting the value of the option
 `mu-registration-file-coding-system-for-read'  properly
 even if they are using one of old (X)Emacsen.
 (mu-registration-file-coding-system-for-read): Fix a
 doc-string.
