Subject: [PATCH] t0040: convert all possible tests to use `test-parse-options --expect`
Message-ID: <01020157c8505fc5-cb313aa8-0182-4e19-95fa-cb36c573ee4c-000000@eu-west-1.amazonses.com>
URL: https://gitlist.dev/e/01020157c8505fc5-cb313aa8-0182-4e19-95fa-cb36c573ee4c-000000%40eu-west-1.amazonses.com

```
Use "test-parse-options --expect" to rewrite the tests to avoid checking
the whole variable dump by just testing what is required. This commit is
based on 8ca65aeb (t0040: convert a few tests to use test-parse-options;
Junio C Hamano; May 6, 2016).

Whoa.  Quite a lot of repetitions removed.
