Synopsis:
   set auto_unmark_away [on|off|toggle]

Description:
   When turned on, this will cause the client to unmark the client as
   being away with the server if the SEND_LINE key function is used (in
   other words, if a message is sent to the server).  If off, the client
   will only try to remove its away status with an AWAY is issued with
   no arguments.
