Subject: [PATCH] t1309: document cases where we would want early config not to
die()
Jeff King came up with a couple examples that demonstrate how the new
read_early_config() that looks harder for the current .git/ directory
could die() in an undesirable way.
Let's add those cases to the test script, to document what we would like
to happen when early config encounters problems.
