[PATCH] SQUASH??? allow t0031 to run with any default branch name

[Junio C Hamano <gitster@pobox.com>]

I no longer remember which step in your multi-patch series
introduces this script or these are built-up incrementally, but I've
been carrying this patch at the tip of the series so that merging it
to 'seen' (or any other interation branch) would not make the result
fail depending on the hardcoded default fallback name for the first
branch.  Can you update your series so that I do not have to [*]?

Thanks.

[footnote]

* meaning, either squash into the commit that adds the t0031 test
  script, if the entire test is created in a single commit, or pick
  the parts of this patch apart and sprinkle the fixes to the commit
  that introduces t0031 and subsequent commits that updates it.
