Yeah, I agree the current state is poor.

Definitely an improvement. Though I wonder if we should go further and
show the user the relationship in the documentation explicitly. Like:
color.<system>::
A boolean to enable/disable color in a particular part of Git,
overriding `color.ui` (see `color.ui` for possible values). The
current set of systems is:
advice::
Hints shown with the "hint:" prefix, controlled by
`advice.*` config.
branch::
Output from the linkgit:git-branch[1] command.
...etc...
We could possibly do the same with color.<system>.<slot>. Or maybe even
make a single hierarchical list of systems, and then the color slots
under each. I think if our mental model in adding these options is
to have this kind of hierarchy, then it makes sense to communicate it
explicitly to the user and get them using the same mental model.
