As a side note, it might actually be an improvement for pgp_verify_tag
to take a sha1 (so that git-tag is sure that it is verifying the same
object that it is printing), but that refactoring should probably come
separately, I think.

Just to be sure, this refactoring is something we should still include
in this set of patches, right? I think that otherwise we'd lose the
desambigutaion that git tag -v does in this patch.

I think it can be part of this series, but doesn't have to be. As I
understand it, the current code is just handing the name to the `git
verify-tag` process, so if we continue to do so, that would be OK.

I also think that most of the rippling is gone if we use and adaptor as
you suggested. Should I add a patch on top of this to support a sha1 as
part for gpg_verify_tag()?

Yes, though I'd generally advise against a function taking either a name or
a sha1, and ignoring the other option. That often leads to confusing
interfaces for the callers. Instead, perhaps just take the sha1, and let
the caller do the get_sha1() themselves. Or possibly provide two
functions, one of which is a convenience to translate the name to sha1
and then call the other.
