I think I'd prefer to delay that part then.
What I'm concerned about if we do have it, is what ordering semantics
there should be, eg for something like:
--sparse-checkout '!X' --sparse-checkout-from F --sparse-checkout Y

Should that be [!X, *F, Y], or [*F, !X, Y], or something else?
Would the option parser need to be modified to handle this?
Or do we just make them mutually exclusive?

The only other clean alternative would be implementing ONLY
--sparse-checkout-from, and letting uses use fds creatively:
--sparse-checkout-from <(echo X; echo Y)
But the msysgit crowd would probably mumble complaints under their
breath at me.
