Øystein Wallegit branch -vv will show "gone" next to a remote tracking branch if it does not exist. for-each-ref is suitable for parsing but had no way of showing this information.
This introduces "%(upstream:gone)" to display "gone" in the formatted output if the ref does not exist or an empty string otherwise, analogous to git branch -vv.
Signed-off-by: Øystein Walle <oystwa@gmail.com> --- I took the liberty of sending in a v2 on my own. Removed the last argument to stat_tracking_info() and used test_config instead of test_when_finished.
