I think it would print "gone" if the upstream branch went missing. But
in this case the actual local branch is missing. And for-each-ref will
not show an entry at all for a ref that does not exist. The
"refs/heads/master" on your command line is not a ref, but a pattern,
and that pattern does not match anything. So it's working as intended.
I think a more direct tool would be:
git rev-parse --symbolic-full-name master@{upstream}
That convinces branch_get_upstream() to return the value we want, but
sadly it seems to get lost somewhere in the resolution process, and we
spit out an error. Arguably that is a bug (with --symbolic or
--symbolic-full-name, I think it would be OK to resolve names even if
they don't point to something, but it's possible that would have other
unexpected side effects).
