Detailed output should include child test descriptions

[thlorenz]

When running the below with node tapme.js

// tapme.js
var test = require('tap').test;

test('parent test description', function (t) {
  t.plan(2)
  t.ok(true, 'test in parent')
  t.test('child test description', function (t) {
    t.plan(1)
    t.ok(true, 'test in child')  
  })
})

it outputs:

TAP version 13
# parent test description
ok 1 test in parent
ok 2 test in child

1..2
# tests 2
# pass  2

# ok

It would be nice if it could include the child test description before test 2, e.g., :

TAP version 13
# parent test description
ok 1 test in parent
# child test description  
ok 2 test in child

[...]

If you agree that this is a valid request I'd be willing to fix it myself and submit a PR, just wanted to get your opinion on this first.

Yes. Child test names should be emitted as comments.

Any plans on pulling this in or suggestions in case improvements are needed?
