It colors everything marked with a "#" as blue (which is also how I have
my color.status.header configured).

Yes, I should have been more clear. _Both_ cases can be a regression,
depending on the user's config; the only way to avoid a regression is to
default to "same as color.status.header".

I see your reasoning, but as someone in the "former" group of your
description, I consider the default of "plain" worse than not
highlighting it at all. Mostly because the _rest_ of my terminal output
tends to be plain, so rather than appearing highlighted, the branch name
appears to be connected to that output. It's hard to describe in words
how ugly it is, but try:
mkdir foo && cd foo && git init
git config color.status.header blue
git status
Maybe we should put this on top?

Subject: [PATCH] default color.status.branch to "same as header"
This gives it the same behavior as we had prior to 1d28232
(status: show branchname with a configurable color).
To do this we need the concept of a "NIL" color, which is
provided by color.[ch]. The implementation is very simple;
in particular, there are no precautions taken against code
accidentally printing the NIL. This should be fine in
practice because:
1. You can't input a NIL color in the config, so it must
come from the in-code defaults. Which means it is up
the client code to handle the NILs it defines.
2. If we do ever print a NIL, it will be obvious what the
problem is, and the bug can be fixed.

I resisted the urge to make a generic "same as $X" token, which would
allow users to do something like:
[color "status"]
branch = from:color.status.header
if they really wanted. But that would be a lot more code, and I'm not
sure it would be all that useful (it would be if people did stuff like
theming git colors like they do window managers, but I don't think we
are at quite that level).
This is simple, solves the current regression, and provides an easy
blueprint for handling the case in the future.
