The partial solution would look like something below. It's not too bad
because git-tag always knows that it's working a ref in the refs/tags
namespace (and we don't even have to qualify it ourselves,
for_each_tag_name already does it for us).

But verify-tag feeds arbitrary sha1 expressions. See the notes in the
second patch.

  [1/2]: ref-filter: split ref_kind_from_filter
  [2/2]: tag: send fully qualified refnames to verify_tag_and_format
