Subject: [PATCH 22/27] pathspec: ensure full index
Message-ID: <f4c470686b2764a6046c8a8b80f18c882ad8899b.1615929436.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.906.git.1615929435.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

Before iterating over all cache entries, ensure that a sparse index is
expanded to a full index to avoid unexpected behavior.
