From: Elijah Newren <newren@xxxxxxxxx>
If commands like merge or rebase materialize files as part of their work,
or a previous sparse-checkout command failed to update individual files
due to dirty changes, users may want a command to simply 'reapply' the
sparsity rules. Provide one.

+'reapply::
+ Reapply the sparsity pattern rules to paths in the working tree.
+ Commands like merge or rebase can materialize paths to do their
+ work (e.g. in order to show you a conflict), and other
+ sparse-checkout commands might fail to sparsify an individual file
+ (e.g. because it has unstaged changes or conflicts). In such
+ cases, it can make sense to run `git sparse-checkout reapply` later
+ after cleaning up affected paths (e.g. resolving conflicts, undoing
+ or committing changes, etc.).
+
'disable'::
Disable the `core.sparseCheckout` config setting, and restore the
working directory to include all files. Leaves the sparse-checkout
