ash: [VAR] Move unsetvar functionality into setvareq
Upstream commit: Date: Tue, 25 May 2010 20:55:05 +0800 [VAR] Move unsetvar functionality into setvareq This patch moves the unsetvar code into setvareq so that we can no have a pathological case of an unset variable hanging around unless it has a bit pinning it like VEXPORT.
