[0/4] Sparse checkout completion fixes

Message

This fixes a few issues with tab completion for the sparse-checkout command,
specifically with the "add" and "set" subcommands.

The 4th patch should probably be considered RFC; it is notable in that we
previously discussed a much different proposal and the general problem
area[1], though our discussion was from a limited vantage point and none of
us (myself included) were aware of the full context at the time. In that
thread, Junio gave some helpful general high-level guidelines for
completion. I believe the existing completion rules fail Junio's guidelines
pretty badly and that we thus need to do something else. See the lengthy
commit message. I implement a simple though somewhat suboptimal choice for
that something else (while arguing that it's at least much better than our
current solution), while also documenting with a code comment a much more
involved alternative solution that we could consider in the future. Comments
on this choice welcome.
