This makes one wonder what would/should be shown on the "A." column
if one of these files are added with "-N" (intent-to-add).  I do not
see any test for such entries in this patch, but I think it should.

I must admit that I don't use -N, so I'm open to recommendations here.
In my brief testing, the existing porcelain status reports it as "AM"
(for both a file with content and an empty file).

The V2 code outputs the following:
1 AM N... 000000 100644 100644 0000000000000000000000000000000000000000 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 intent.add

Which I think makes sense.  I'll add a test to exercise that.


"Try -z on the above" can and should be in the test title to help
...
Having said all that, it is OK to fix their titles after the current
9-patch series lands on 'next'; incremental refinements are easier
on reviewers than having to review too many rerolls.

I'll change the test titles to have all that info.


This is probably a good place to see what happens to these untracked
files and branch info if we do not ask the command to show them.

I'll add some cases to cycle thru the options and confirm
there's no output when not requested.

Arrange these files to be cleaned before you create them by having

	test_when_finished "rm -f x.ign .gitignore" &&

at the very beginning of this test before they are created.
Otherwise, if any step before these removal fail, later test that
assume they are gone will be affected.  You already do so correctly
in the upstream_fields_0 test below.

Missed a few.  Got it.  Thanks!

+	EOF

This is a small point, but doesn't the lowercase 'u' somehow look
ugly, especially because the status letters that immediately follow
it are all uppercase?


Since we are inventing a new format and my column 1 is completely new
I didn't think it mattered. And I used a lowercase 'u' to distinguish it from the "U" in the X and Y columns since they mean different things.

But we can change it if you'd prefer.


+	git status --porcelain=v2 --branch --untracked-files=all >actual &&
+	git reset --hard &&

This "reset" also may be a candidate for test_when_finished clean-up
(I won't repeat the comment but there probably are many others).

Got it. And I hopefully caught the rest.


+test_expect_success 'upstream_fields_0' '
+	git checkout master &&
+	test_when_finished rm -rf sub_repo &&

The "when-finished" argument are usually quoted like this, I think:

	test_when_finished "rm -rf sub_repo" &&

Got it. Thanks.


I have the test changes ready.  As suggested, I'll send a single commit
patch after my 9-patch series lands on 'next'.

Thanks,
Jeff
