======Synopsis:======
[[on]] [<modes>]exec_exit [<serial#>] [-|^]<match> { <action> }

======Description:======
This hook is triggered whenever an [[exec command|EXEC]]ed process finishes,
either because it exits, it is killed by a signal, or you asked the client 
to disown it.

This hook is always thrown, no matter what the value of 
[[set notify_on_termination]] is.

======Parameters:======
|$0    |process number or name of the [[exec command|EXEC]]ed process     |
|$1    |signal that killed the process, or 0 (zero) if it exited normally |
|$2    |exit code (usually zero, unless $1 is non-zero)                   |

======Default behavior:======
If you do not suppress this event, the client will format the message
and display it to your screen **UNLESS** [[set notify_on_termination]] 
is OFF.

======Examples:======
To display when a process exits:
   on ^exit_exec "*" {
      if ( [$2] ) {
         xecho -b Process '$0' exited with code $2 \(signal $1\)
      } {
         xecho -b Process '$0' exited normally
      }
   }

======History:======
The [[ON EXEC_EXIT]] hook first appeared in ircII.
