cat-file ambiguity prints "dangling"

Hi David,

Perhaps I'm confused, the cat-file manpage seems to indicate "dangling" only gets printed if I use "--follow-symlinks".

However, I'm not using "--follow-symlinks" and I get "dangling" when passing ambiguous object IDs:

Trying to check the ambiguous "dead" against git.git, I get:

	$ echo dead | git cat-file --batch-check 2>/dev/null
	dangling 4
	dead

Is the above intended?

stderr shows the ambiguity and gives me hints, which is expected.

Thanks.
