[PATCH 00/10] describe tests: refactor & fix recent broken tests

While looking at the "git describe" tests due to the on-list %(describe) discussion I discovered that the feature added in 30b1c7ad9d (describe: don't abort too early when searching tags, 2020-02-26) has never been tested for.

This is because it defined a custom test function that called test_expect_success, which then got called inside another top-level test_expect_success. Thus even if it failed we'd pass the test.

This series fixes that issue, and makes some general improvements to the "describe" tests. I then make test_expect_{success,failure} return 1 to catch these sorts of issues in the future, which required fixes to a couple of svn tests that ran with "set -e".

I was on the fence about whether to send this after the recent rc0, but figured that since it's test-only Junio might want to pick it up, and possibly for the next rc in case we'd like to do some pre-release testing for this never-before-tested feature added in 2.26.0 (although the actual implementation looks fine to me).
