[PATCH] Demonstrate broken t6001 test case function

Junio discovered a problem where an actual test case break was hidden
because pipelines are not handled properly by the test infrastructure in
t6001.

This patch fixes the broken infrastructure (and demonstrates the break
explicitly).

A subsequent patch in this series will fix the test case so that it
doesn't fail.
