[PATCH 15/19] tree-diff: no need to call "full" diff_tree_sha1 from show_path()

As described in previous commit, when recursing into sub-trees, we can
use lower-level tree walker, since its interface is now sha1 based.

The change is ok, because diff_tree_sha1() only invokes
__diff_tree_sha1(), and also, if base is empty, try_to_follow_renames().
But base is not empty here, as we have added a path and '/' before
recursing.
