Subject: [PATCH 12/27] ls-files: ensure full index

From: "Derrick Stolee via GitGitGadget" <[email-masked]>
Date: Tue, 16 Mar 2021 21:17:00 +0000

From: Derrick Stolee <[email-masked]>

Before iterating over all cache entries, ensure that a sparse index is
expanded to a full one to avoid missing files.
