With the new --verbose-only=<pattern> option, one can enable --verbose
at a per-test granularity. The pattern is matched against the test
number, e.g.
./t0000-basic.sh --verbose-only='2[0-2]'
to see only the full output of test 20-22, while showing the rest in the
one-liner format.
As suggested by Jeff King, this takes care to wrap the entire
test_expect_* block, but nothing else, in the verbose toggling. We
can use the test_start/end functions from the previous commit for the
purpose.
This is arguably not *too* useful on its own, but makes the next patch
easier to follow.
