[PATCH] git-rev-list: Don't die on a bad tag

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

The current cogito tree contains an invalid tag
(junio-gpg-pub => 0918385dbd9656cab0d1d81ba7453d49bbc16250), and
git-repack-script (and probably others) will die when git-rev-list
tries to dump the objects.  This patch changes it to complain, but
continue.
