From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
Conflicts can occur outside of the sparse-checkout definition, and in
that case users might try to resolve the conflicts in several ways.
Document a few of these ways in a test. Make it clear that this behavior
is not necessarily the optimal flow, since users can become confused
when Git deletes these files from the worktree in later commands.
