[GSoC] Week 5 and week 6 status update

[Shaoxuan Yuan <shaoxuan.yuan02@gmail.com>]

Hi Git community,

Here is Shaoxuan Yuan.

I'm writing to share my latest progress [1] from GSoC week 5 and week 6.

You can read them when you are free, and generously give me some
advice if possible!

Summary of the two weeks

At this stage, the main focus is on making `git-sparse-checkout` work
better with `git-mv`. After getting the "from out-of-cone to in-cone"
series merged [2] into master, I'm working to make the complementary
"from in-cone to out-of-cone" [3] possible. It's now a [PATCH v1].
Read the previous blogs on GSoC to get a better context.

In the meantime, I'm also experimenting with `git-rm` to integrate with
`sparse-index`. `git-rm` turns out to be a slightly less complex command
in terms of its interaction with `sparse-checkout`, so working with it
at the same time gives me some insight into `sparse-index`, without
worrying too much about its compatibility with `sparse-checkout`.
