This part fixes the --<tab> completion. I suppose if someone
did "-<tab>" then nothing would show up?

With the thinking of rebasing onto en/sparse-checkout-set, this
could possibly be rearranged so the add|set) cases pass-through
into the init) and reapply) cases (skip the ;; between) to save
some duplication. Or, it is possible that doesn't work, but it
might be worth a try.

Also, since you are using 'git ls-tree' and not 'git ls-files',
the sparse index will not have an effect on the performance.
There will be some corner cases where a directory exists in one
of HEAD or the index but not the other. That's probably still
the right way to go since 'git ls-files' doesn't have a way to
only list directories. It just means that you probably don't
need to explicitly disable the sparse index in your test.

Thanks,
