Cannot get status of real git repo

[wyattscarpenter]

Consider the following:

/tmp$ git clone  --recursive https://github.com/thblt/write-yourself-a-git/ w && cd w && make all && ./wyag status
[...]
On branch master.
Changes to be committed:
Traceback (most recent call last):

TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

It's like this for ./wyag log as well.

digraph wyaglog{
  node[shape=rect]

It's also like this for other git repos that I have on my machine that aren't related to wyag

I'm using Ubuntu 24.04.2 LTS via WSL 2.6.3.0 on Windows 10.0.19045.6809. Normal git works great on this, and python generally seems to act exactly like it's on Linux.

Re status, wyag status chokes on submodules -- this can probably be improved with a nicer error, as long as it doesn’t overcomplicate the code. The issue with log is more surprising, I’m looking into it.

This is a packfile issue, I should document this better. See https://wyag.thb.lt/#packfiles
