[PATCH 08/25] t: fix &&-chaining issues around setup which might fail

From

In-Reply-To
<20150320100429.GA17354@peff.net>

Many tests have an initial setup step that might fail based on whether earlier tests in the script have succeeded or not. Using a trick like "|| true" breaks the &&-chain, missing earlier failures (and fooling --chain-lint).

We can use test_might_fail in some cases, which is correct and makes the intent more obvious. We can also use test_unconfig for unsetting config (and which is more robust, as well).

The case in t9500 is an oddball. It wants to run cmd1 _or_ cmd2, and does it like:

  cmd1 || cmd2 &&
  other_stuff

It's not wrong in this case, but it's a bad habit to get into, because it breaks the &&-chain if used anywhere except at the beginning of the test (and we use the correct solution here, putting it inside a block for precedence).
