From d0cd253b37646d9364d046e1d3edb022a58c105a Mon Sep 17 00:00:00 2001

Subject: [PATCH] test: require test_begin_subtest before test_expect_success

Unify the subtests by requiring test_begin_subtest before
test_expect_success. (Similar change for test_expect_code will
follow.)

This increases clarity in the test scripts by having a separate line
for the start of the subtest with the heading, and makes it possible
to simplify the test infrastructure by making all subtests similar.
