[PATCH 3/7] test-lib: color "ok" TAP directives green under --verbose (or -x)

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the color of "ok" lines to be green when we run under --verbose
or -x.

When a test fails we color the "not ok" line red, but the "ok" lines
are not colored.

I think that's the right thing to do in the default output, which is
e.g.:

    $ ./t0000-basic.sh
    ok 1 - verify that the running shell supports "local"
    ok 2 - .git/objects should be empty after git init in an empty repo
    ok 3 - .git/objects should have 3 subdirectories
    [...]

Having almost every line colored green in that output would be
distracting.

However, under --verbose we'll typically might emit 10-20 lines of
non-colored stderr and "info" colored output describing the test
itself.

When paging through that output always having the boundaries between
tests highlighted makes the output more readable.
