Thanks; the first three in the series looks right.

I somehow had an impression that majority of others convinced you to
rename this to default-to-upstream, but I may be mistaken.

I think somebody who does not know the history of the development and
discussion of this feature would think that this specifies the default
upstream remote (i.e. not a boolean variable, but a string) given this
name.

It is somewhat rude to reviewers' eyes to turn an existing "if" into "else
if" and place new stuff at the beginning; unless there is a good reason
that the new stuff has to be at the beginning, that is.

This is not a new issue, but a callback function to git_config() should
return once it recognized and handled the variable, instead of cascading
the controll out.  The "diffstat/stat" code shows a bad example and you
inherited the badness from there.
