[PATCH 0/4] Sparse checkout completion fixes

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.
