/*
 * cmd_tell - Handle the "!tell <nick> <message>" command.

 * <nick> when they're around." Rate-limited.
 *
 * Parameters:
 *   s            - The IRC session.
 *   msg          - The raw IRC message text.
 *   reply_target - Channel or nick to send the response to.
 *   src_nick     - The nick of the user who issued the command.
 *
 * Returns: 1 if the command was matched, 0 otherwise.
