From b52d704e8894a72d7caefea40bbd3677ea0bd3e0 Mon Sep 17 00:00:00 2001
From: Zac Medico <zmedico@gentoo.org>
Date: Thu, 27 Jul 2006 06:20:11 +0000
Subject: [PATCH] Move the initial check of previously fetched files out of the
 locations loop so that that the same code path can be used (patch to follow)
 when fetch is restricted and there are no custom local mirrors.  See bug
 #37455.
