The same as if you didn't have 'branch.foobar.base': none. You get an
error because there's no upstream.

That's what I described in my example.

But it's already broken.

'git pull' is not the same as 'git fetch'+'git merge'. That *only*
works  when merge.defaulttoupstream is set.

Indeed. It wouldn't be an intrusive change; it would only affect 'git
rebase', and nothing more.

But I'm wondering if the behavior of 'git fecth' should change as
well. And in fact it should be the other way around.

But I think the norm would be to have only 'base', because a lot of
people don't manually set an upstream branch.

In the end it all boils down to; which is the upstream
'origin/master', or 'github/master'? Well, it is 'origin/master', so
'upstream' should point there, but I don't want to push to the
'upstream', I want to push somewhere else by default.
