    Fix problem with 8bit content-transfer-encoding in nndoc mbox files
    
    * lisp/gnus/nndoc.el (nndoc-possibly-change-buffer): If we're
    reading an mbox file, it may contain messages that use
    content-transfer-encoding 8bit, which means that we have to treat
    the file as a sequence of byte (bug#42951).  This avoids
    double-decoding -- once by Emacs when inserting the mbox into the
    buffer, and once by Gnus when displaying the articles.
