I think the examples in notes/sparse-directories.txt are probably a good
guide, but don't treat it as a rigid specification: if you think of
something better, we can do that instead.

In other words, you're welcome to submit patches to
notes/sparse-directories.txt as well as to code :-).

Yes. For now, I think we should concentrate on getting the --depth
interfaces to work for deselection. We can worry about aliases later.

That's a good question.

Maybe behave similarly to what 'svn delete' does -- that is, leave the
modified files in place (but in this case, they'd also remain versioned,
unlike with 'svn delete').
