index.deleteSparseDirectories::
When enabled, the cone mode sparse-checkout feature will delete
directories that are outside of the sparse-checkout cone, unless
such a directory contains an untracked, non-ignored file. Defaults
to true.

index.recordEndOfIndexEntries::
Specifies whether the index file should include an "End Of Index
Entry" section. This reduces index load time on multiprocessor
