Subject: [alpine-devel] [PATCH] list: Detect orphaned packages correctly

From: "A. Wilcox" <[email-masked]>
Date: Thu, 21 Mar 2019 18:42:32 -0500

BIT(1) corresponds with decimal 2, which is the first available repository.
BIT(0) corresponds with decimal 1, which is the installed repository.

Before this fix, `apk list -O` would list every package installed from the
first available repository, which is the 'system' repository on most Adélie
Linux computers.

After this fix, `apk list -O` correctly lists only the packages which are
no longer available.
