Be careful when dereferencing tags.
One caller of deref_tag() was not careful enough to make sure what deref_tag() returned was not NULL (i.e. we found a tag object that points at an object we do not have). Fix it, and warn about refs that point at such an incomplete tag where needed. Signed-off-by: Junio C Hamano <junkio@cox.net>
