From 16efdb5ec7f28bed9541fc773330e3e2ebe2ed9a Mon Sep 17 00:00:00 2001
From: Neil Conway <neilc@samurai.com>
Date: Thu, 26 Apr 2007 16:13:15 +0000
Subject: Rename the newly-added commands for discarding session state. RESET
 SESSION, RESET PLANS, and RESET TEMP are now DISCARD ALL, DISCARD PLANS, and
 DISCARD TEMP, respectively. This is to avoid confusion with the pre-existing
 RESET variants: the DISCARD commands are not actually similar to RESET. Patch
 from Marko Kreen, with some minor editorialization.
