Mentioned elsewhere, but I think the above should be

	if (!path)
        	path = obj_context.path;

	if (obj_context.mode == S_IFINVALID)
        	obj_context.mode = 0100644;

IOW, even when there is an explicit path supplied, we should fall
back to assumed "regular blob" mode, so that

	git cat-file --filters --path=README $(git rev-parse :README)

would work as expected.
