Hm, maybe --format is all that's necessary to resolve the concerns about
errors affecting scenario (a) ?  If that's the case, then maybe the path
forward is a warning on tagname mismatch (and maybe i can convince you
later than an actual error could be acceptable :P)

But I don't see how to use --format with "git tag -v" at all.  Can you
show me what i'm doing wrong?  git-tag(1) says that --format defaults to
'%(refname:strip=2)', but git tag -v behaves differently when i specify
that same default explicitly:

    0 dkg@alice:~/src/pkg-gnupg/gnupg2$ git tag -v gnupg-2.2.13
    object 7922e2dd1c7eee48a8a2cf4799827942489ddd0f
    type commit
    tag gnupg-2.2.13
    tagger Werner Koch <wk@xxxxxxxxx> 1549985965 +0100

What am i missing?
