[PATCH] git checkout's reflog: even when detaching the HEAD, say from where

From: Johannes Schindelin <johannes.schindelin@gmx.de>
Date: Aug 7, 2007, 01:42 UTC
Message-ID: <Pine.LNX.4.64.0708070242140.14781@racer.site>

When checking out another ref, the reflogs already record from which branch you switched. Do that also when switching to a detached HEAD.
