Subject: git-show: do not segfault when showing a bad tag
X-Git-Tag: v1.6.0.6~9
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/d2dadfe890b5da6f65fe061a414b6ec67c5efe9c?hp=d2dadfe890b5da6f65fe061a414b6ec67c5efe9c

git-show: do not segfault when showing a bad tag

When a tag points at a bad or nonexistent object, we should diagnose the
breakage and exit.  An earlier commit 4f3dcc2 (Fix 'git show' on signed
tag of signed tag of commit, 2008-07-01) lost this check and made it
segfault instead; not good.

This fixes it.
