[GSoC] Week 3 and week 4 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 3 and week 4.

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

Summary of the week 3 and week 4

At this stage, the main focus is on making `git-sparse-checkout` work better
with `git-mv`. With the ongoing "from out-of-cone to in-cone" clearing
up, I'm also working to make the complementary "from in-cone to out-of-cone"
possible. Read the previous blogs on GSoC to get a better context.

In the meantime, some experiments towards integration with `sparse-index`
have also started, which are based on the latest work "from in-cone to
out-of-cone" boiling in my branch.

This week I'm working to ship a PATCH v5 [2] (please reference all the
code here) to address the issues raised in PATCH v4 [3].

The good news is, that PATCH v5 is being queued into the 'next' branch, 
which
means it could potentially be merged into 'master'. It marks that this stage
of work is almost done.
