Fix off by one error in test

It doesn't affect the test outcome, but it is not the intended behaviour of
the test.

We listen once to find out what port to use, then should bind with SO_REUSEPORT
N-1 times, but we are doing it N times, so we have one extra listener.

Commit objects reference one tree, and zero or more parents.

Single parent commits can typically generate a patch in
unified diff format via `git format-patch'.

Multiple parents means the commit is a merge.

Root commits have no ancestor.  Note that it is
possible to have multiple root commits when merging independent histories.

Every commit references one top-level tree object.
