I'd like to simply ignore them. Only if you still have the tree references they came from. In other words, once you *only* have the SHA1, you're kind of screwed, because by that time you've lost the context, and the SHA1 itself contains no information about what kind of thing it is. But when running git-diff-tree, you still have the source of the SHA1, and the tree entry in particular. The tree entry will have a "gitlink" marker, ie the "mode" will be 0160000.
