I am considering this, it would hide the change_table as that doesn't
need to be exposed (for now at least). My only concern is that it
would make the commit-msg rather unwieldy.

I don't know to be honest, the call site always seems to pass one in.
Changed it to BUG.

Maybe you can help me find a bug. If you run `git-change update`
twice without changing commits, it prints that it created a second
one, but then if you `git-change list` it doesn't show that last one
because it doesn't create an extra one if there's already a change
pointing at HEAD.
Also, thanks for all the comments, it's helping my understanding too.
In general do you want all these comments added to the code?

Yes, this is consumed in the change.c command. I was considering
making this a strintmap that maps to an enum, because we need a
tristate (updated, created, untouched). But unfortunately the oids
assigned to `->util` are consumed later in the function.

Sounds like a potentially good idea, to avoid that people accidentally
create metacommits that aren't real.
What would that look like on the parsing side as well as the test-setup?

So the change command uses the changes list to determine what to print
to the output. It looks whether it's a new change or a created change
based on whether the oid is null or not.
We could return a strintmap instead that points at status per change.
I tried that approach but unfortunately, `changes` is used later in
this function. I could still consider a strintmap, it would just be
that there's some duplicative storage of information until the
function exits. LMKWYT.

Turns out the change command needs the `changes` string_list. I've
made this one private and extended the public one with the changes
list.
I could potentially still return a strintmap but I'm on the fence.
