Unfortunately, we need the simplified version, because we otherwise
don't know what the ..s are relative to in the case of a link to a link:
echo content >dest ;# actual blob
mkdir -p foo/bar
ln -s foo/bar/baz fleem # in-tree link-to-link
ln -s ../../../external foo/bar/baz # out-of-tree link
If echo HEAD^{resolve}:fleem were to return ../../../external (after
following the first symlink to the second), we would have lost
information.
