OK.

Is this "git config" necessary, or is it a remnant of a debugging
session?  It is tested in the helper that branch.track.merge is set
to something, and otherwise the helper would fail the same way as
this standalnoe "git config" would, no?

It is true that this test helper must yield failure.  But what you
expect probably is more than that, no?  For example, the test helper
would fail even if branch.foo.remote is set to the upstream as long
as branch.foo.merge is not set to point at their foo, but what you
really want to make sure is that neither configuration variable is
set.
