[PATCH 3/3] Ignore no-op changes in paranoid update hook

From: Shawn O. Pearce <spearce@spearce.org>
Date: May 26, 2008, 02:18 UTC
Message-ID: <20080526021805.GC29990@spearce.org>

If the hook gets invoked with identical old and new ids there is no change taking place. We probably should not have been called, but instead of failing silently allow the no-op.
