I think we are in agreement and I do not see how you can draw
different conclusions.  The above argument refutes the point Michael
made a big deal out of, which was that "these are individual and
independent bools in the implementation detail of the code, expose
that as such to the end users."  I do not buy that point, i.e. it is
not a good argument to favor style 2 over style 1, which was the
primary thing I wanted to illustrate in the message you are
responding to.

Isn't it cumulative?  At least it should be (but I wouldn't be too
surprised if the recent config reader caching broke it).

If that becomes an issue, "git config" would have to learn about
them, just like it knows about how to do --color depending on the
tty-ness of the output.

See above 1.

I have no strong opinion.  It was primarily meant to illustrate why
pager.<cmd> and alias.<cmd> were bad precedents that should not be
used to support design of future things.
