    Fix info-apropos when the default encoding is Latin-N
    
    * lisp/info.el (Info-find-node-2): Reset the buffer's encoding to
    'undecided', so that it is set to the encoding of the Info file we
    are about to insert.  Otherwise, 'info-apropos' will fail to find
    some index nodes in some UTF-8 encoded files, if the buffer's
    previous encoding is Latin-N or some such.
