   +
   +    telnet: Use memove for overlapping memory instead of strncpy.
   +
   +    Overlapping source and destination buffers are not supported
   +    by strncpy and give undefined results.
   +
   +    7.24.2.3 of ISO/IEC 9899:201x:
   +    "If  copying  takes  place  between  objects  thatoverlap,
   +    the behavior is undefined."
   +
   +    * telnet/commands.c (cmds): Use memove for overlapping memory
   +    instead of strncpy.

LGTM, please commit to master.
