Synopsis:
   set history [<positive number>]

Description:
   This setting controls the maximum number of entries to be stored in 
   the client's history buffer.  Setting it to 0 (zero) purges the history
   buffer and disables command history.

   Historical ircII behavior was to have the history buffer managed by a file
   that each entry was written to.  Interacting with the history (via the
   BACKWARD_HISTORY and FORWARD_HISTORY keybindings) used this file.  This
   meant that multiple invocations (processes) of the ircII client used a
   shared, global history across all screens, across all clients.  EPIC does 
   not use a file as a "backing store" for the history, and so each invocation 
   of the client has its own separate history.

   The contents of input line are inserted into the history buffer every 
   time one of the following things happen:
	* The SENDLINE key binding is used
	* The SHOVE_TO_HISTORY key binding is used
	* The BACKWARD_HISTORY key binding is used
	* The <return> key is used when EPIC is in "dumb mode"
