Great question.  I think "git diff" with various options would also
want to optionally be able to be confined within the sparse cone, or
checking the entire world by lazily fetching outside the sparsity.

I am not sure which one should be the default.  From historical
point of view that sparse stuff was done as an optimization to omit
initial work and lazily give the whole world, I may have slight
preference to the "we pretend that you have everything, just some
parts may be slower to come to you" world view to be the default,
with an option to limit the view to whatever sparsity you initially
set up.  Regardless of the choice of the default, it would be a good
idea to make the subcommands consistently offer the same default and
allow the non-default views with the same UI.
