618310a (t6302: skip only signed tags rather than all tests when GPG

Should we cite bc9acea (ref-filter: implement %(if), %(then), and
%(else) atoms, 2016-04-25) here as an example of a commit for which

unavailable)?

To make this as close to a reversion as possible, this could be
restored to the original (sans 'cat'):

    sed -e "s/Z$//" >expect <<-\EOF &&
