Synopsis:
   dcc close <type> <nick> [<arguments>]

Description:
   DCC CLOSE closes an unwanted DCC connection, or cancels a pending one.
   The type, nickname, and parameters required are the same as those
   shown in DCC LIST output.  If no arguments are specified, the oldest
   DCC record for the given type and nick is closed.

   When DCC CLOSE is used on a pending incoming connection (one that has
   not yet been established), it is treated as a rejected connection, and
   a message to that effect is send back to the remote client.  Note that
   for an incoming SEND, the client actually records it as a GET, since
   from a local perspective, the client will be getting something from
   the remote client.
   
   DCC CLOSE can also accept the flag '-all' or an asterisk, '*', as either
   the type or the nickname.  This will work as a wildcard, closing all DCC's
   from that type or nickname.

Examples:
   To close an existing DCC CHAT connection with joebob:
      /dcc close chat joebob

   To reject an incoming DCC SEND connection from joebob:
      /dcc close get joebob

   To close all DCC CHAT connections:
      /dcc close chat *
         or
      /dcc close chat -all
