Nit: in this loop there's already the synonym 'path' for item.match,
so perhaps

			if (!seen[i] && path[0] && ...)

would be clearer.

Should "git add --refresh ." get the same treatment?

Adding a test at the end like this means the tests come in chronological
order instead of logical order and simultaneous patches to the same
test script become more likely to conflict.
