stringify: fix arrayFormat comma with empty array/objects

[daggerjames]

Fixed #310

continued from PR #317

Why did you open a second PR? That creates a permanent pollution in the repo refs that can never be removed.

Please never ever make a duplicate PR.

@daggerjames hey, sorry for the delay here :-)

I've rebased this; the first commit is awesome and good to go; for the second one, 3 of your new tests are failing - and it seems like the tests are correct. Can you take a look?

[daggerjames]

fixed all tests. Seems logical error with previous approach.
could you please rebase the branch for me? thanks. I'm still unfamiliar with those rebase things and might lose it like what I did last time

Thanks~

[ljharb]

Not stoked on the "use an object as a sentinel key" but it seems straightforward enough, and tests pass.

Thanks, and sorry for the repeated delays :-)

Hi @ljharb, sorry to bother you, but were these changes published to npm? I can still reproduce the original behavior from the latest published version.

See this failed test (extracted from this pull request)

[ljharb]

No; this hasn’t been published yet.
