The point being that if you want to test whether you have the thing the 
tag _points_ to, you should verify it.

And that's where the "--verify" flag comes in:

	[torvalds@g5 linux]$ git-rev-parse v2.6.11^0 ; echo $?
	error: Object 5dc01c595e6c6ec9ccda4f6f69c131c0dd945f8c is a tree, not a commit
	v2.6.11^0
	0

and if the object the tag points to didn't exist at _all_ in your object
store, you'd have silently gotten

	[torvalds@g5 linux]$ git-rev-parse v2.6.11^0 ; echo $?
        v2.6.11^0
        0

but if you used "--verify", you'd have at least gotten

	[torvalds@g5 linux]$ git-rev-parse --verify v2.6.11^0 ; echo $?
	fatal: Needed a single revision
	1

which is what you want, I thought.
