An index entry typically represents a file. However, if sparse-checkout 

is enabled in cone mode (`core.sparseCheckoutCone` is enabled) and the
`extensions.sparseIndex` extension is enabled, then the index may
contain entries for directories outside of the sparse-checkout definition.
These entries have mode `040000`, include the `SKIP_WORKTREE` bit, and
the path ends in a directory separator.
