Hmm. So this sounds like the minimum thing to implement "branch -vv" output, but it feels sort of weirdly non-orthogonal. I guess you'd say: %(upstream:track)%(upstream:gone) and assume that only one of them will show any data. I almost wonder if %(upstream:track) should just output some specific token for the "gone" case, which matches what "branch -vv" does. (I'm also not sure we can match "branch -vv" exactly here anyway, as it looks like "[%(upstream): %(upstream:track)"], but our "%(upstream:track)" uses its own brackets.) I suppose that is a backwards-incompatible change for "%(upstream:track)", but I'm not sure how much we have promised about its format.

Maybe you could even use a new branch name, which makes test_config applicable again: cat >expected <<-\EOF && master no-upstream gone EOF git branch refs/heads/no-upstream && test_config branch.no-upstream.remote . && test_config branch.no-upstream.merge refs/heads/does-not-exist && git for-each-ref --format="%(refname:short) %(upstream:gone)" >actual && test_cmp expected actual -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
