Re: Pretty date option for git tag?

It seems like you should be able to script around for-each-ref and
remain efficient, but I don't think there is a way to convince it to
dereference tags. Something like:

  git for-each-ref --format='%(refname)
  Tag: %(taggername) %(taggeremail) %(taggerdate)
  Commit: %(authorname) %(authoremail) %(authordate)
  ' refs/tags

almost works, but the commit fields are always empty. So I think you
would have to parse and manually rev-parse each one.

PS The for-each-ref command above caused a segfault when run in git.git.
