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.
