        * remote.c: merged.

        - Jim Blandy  <jimb@zwingli.cygnus.com>
        (print_packet, remote_packet_command): New functions.
        (_initialize_remote): Register the remote-packet command.
        - David Taylor  <taylor@texas.cygnus.com>
        (_initialize_remote): remote-compare is now
        compare-sections.
        - Elena Zannoni  <ezannoni@kwikemart.cygnus.com>
         (remote_compare_command): added warning, issued in case
        of mismatch only.
